| braddr | fabbione: have you ever built a linux/sparc kernel from solaris/sparc? I'm gonna try to see if I can gather some more debugging info. Dave doesn't believe he'll have time before I have to return the box. | 05:35 |
|---|---|---|
| braddr | or from linux/x86, for that matter | 05:35 |
| fabbione | braddr: well i did from linux arch foo to sparc | 07:56 |
| fabbione | but not from solaris | 07:57 |
| fabbione | google for crosstoolchain | 07:57 |
| === braddr nods. compiling from solaris is proving to be rather painful | ||
| fabbione | no wonder | 08:28 |
| fabbione | if you have a patch i can build a kernel for you | 08:28 |
| fabbione | it takes me only a few minutes here | 08:28 |
| fabbione | or something you want to play with | 08:28 |
| braddr | well, I want to turn on all the debug options and probably add a bunch of printfs around the point of failure.. so the ability to iterate and build the net boot images on demand | 08:29 |
| fabbione | yeah i understand that | 08:30 |
| fabbione | hmm | 08:30 |
| fabbione | if you have a'linux box, just build the cross compile tools | 08:30 |
| fabbione | it's really easy to do | 08:30 |
| === braddr nods, "just never have before. :)" | ||
| fabbione | braddr: there is a set of scripts that do that for you. it's one of the first hits on google :) | 08:31 |
| braddr | building gcc and glibc.. this might just take a little while. | 08:39 |
| fabbione | yeah it doesn't take that long.. iirc it disables the test suite | 08:42 |
| braddr | while this is running, if you feel like spinning a build with all the debug options turned on that might give something to go on. If I recall correctly, we were suspecting memory corruption, so CONFIG_DEBUG_SLAB, CONFIG_DEBUG_VM, CONFIG_DEBUG_PAGEALLOC, and maybe CONFIG_DEBUG_BOOTMEM might be interesting. | 08:44 |
| fabbione | yes.. i can do that | 08:44 |
| braddr | have you seen other reports of boot problems or successes with 16 cpu models? | 08:45 |
| fabbione | not one :( | 08:45 |
| fabbione | but i did add you to the Release Notes | 08:45 |
| braddr | that's unfortunate | 08:45 |
| fabbione | * SUN T2000 with 4 cores have been reported as not working. | 08:45 |
| fabbione | ok give me a sec and i will build for you | 08:47 |
| fabbione | more than a sec | 08:47 |
| fabbione | i need to power up everything | 08:47 |
| braddr | no hurry.. the scripts are running to build the sparc64 tool chain | 08:48 |
| fabbione | braddr: i assume you did try already to boot the latest installer... | 08:54 |
| braddr | I haven't tried anything since we last worked on this.. been sticking with solaris. | 08:54 |
| fabbione | can you try just in case? | 08:55 |
| braddr | sure | 08:55 |
| fabbione | http://archive.ubuntu.com/ubuntu/dists/dapper/main/installer-sparc/current/images/sparc64/netboot/2.6/ | 08:55 |
| fabbione | may never know it was "auto-fixed" | 08:55 |
| braddr | stranger things have certainly happened | 08:56 |
| braddr | fetching now | 08:56 |
| fabbione | yup | 08:56 |
| === fabbione hates the console with all the his heart | ||
| === braddr had forgotten how quiet it was when the beast is off. | ||
| fabbione | eehhe | 09:03 |
| fabbione | i had it turned on for the last few days together with the SAN | 09:03 |
| fabbione | to do test installs for release | 09:03 |
| fabbione | i can't hear my wife anymore.. and that's good... ;) | 09:04 |
| fabbione | not sure i will be able to hear anything anylonger.. | 09:04 |
| braddr | mine's been on for weeks | 09:04 |
| fabbione | no i power it off when i don't need it | 09:04 |
| fabbione | i did rebuild all of the 9000 pkgs of dapper in 36 hours flat on my T2000 :) | 09:05 |
| fabbione | with 2 of them you could make a port of a distro in a day | 09:05 |
| braddr | a few additional messages in the boot log, but dies with essentially the same error, but no stacktrace | 09:06 |
| fabbione | ok | 09:06 |
| braddr | before: | 09:07 |

| fabbione | where you running slowlaris before rebooting in Linux? | 09:09 |
| braddr | thought you might like the user space part. :) | 09:09 |
| braddr | yes | 09:09 |
| fabbione | can you please poweroff -> poweron -> boot ? | 09:09 |
| braddr | roger | 09:09 |
| braddr | what was the openboot command to disable auto booting? | 09:09 |
| braddr | set auto-boot false? | 09:09 |
| fabbione | like if i remember.... hold on :) | 09:10 |
| fabbione | setenv auto-boot false? | 09:10 |
| braddr | looks like it's already set that way from last time. | 09:11 |
| braddr | powering back on.. 10 minutes to info. :) | 09:12 |
| fabbione | take your time | 09:12 |
| fabbione | i am still installing kernel b-d | 09:12 |
| fabbione | the machine was in an interesting state today after a few tons of installs | 09:13 |
| braddr | hrm.. looks like the crosstool build blew up while building the kernel | 09:14 |
| fabbione | that's no surprise.. the kernel config is crap there iirc | 09:14 |
| braddr | I'll poke at the script and see how to disable building the kernel and glibc.. all I need is gcc | 09:15 |

| braddr | the last line repeats | 09:20 |
| fabbione | ok | 09:20 |
| fabbione | it's that "killed" before | 09:20 |
| fabbione | but at least it looks less scary | 09:20 |
| fabbione | ok building the kernel now | 09:21 |
| braddr | there isn't a SUN4V-DTLB part this time | 09:21 |
| fabbione | yes | 09:21 |
| fabbione | i can see that :) | 09:21 |
| fabbione | it's probably being catched by syslog or klogd | 09:21 |
| === braddr nods, just confirming that I didn't leave it out. | ||
| fabbione | that's why i told you to poweroff | 09:21 |
| fabbione | sometimes slowlaris leave the CPU in an "interesting" unresettable state (for linux) | 09:22 |
| fabbione | i think somehow the main issue has been solved but there is still something fishy going on. otherwise you would have seen the same problem | 09:23 |
| fabbione | TBH if i was you i would try yet another reboot.. just to enjoy the 4 secs of silence between reboots | 09:24 |
| fabbione | no seriously.. i would like to see another reboot | 09:24 |
| fabbione | to see if the DTLB error comes up again | 09:24 |
| fabbione | sometimes it's just a matter of timing with syslog starting | 09:24 |
| braddr | oh.. you wanted it w/o the powercycle? | 09:24 |
| fabbione | powercycle was perfectly fine | 09:25 |
| fabbione | just do another one now | 09:25 |
| braddr | ok.. in progress. | 09:25 |
| fabbione | what we want to try to see if syslog is hiding it or not | 09:25 |
| fabbione | given that we can't access the logs once it crashes | 09:25 |
| braddr | it might be interesting to see if two boots back to back w/o a powercycle gets the original error | 09:25 |
| fabbione | up to you | 09:25 |
| fabbione | the kernel here is almost done | 09:26 |
| braddr | past post, into the linux boot now | 09:31 |
| fabbione | :) | 09:31 |
| braddr | crosstool past a stupid linux source bug and into building binutils | 09:32 |

| fabbione | yup | 09:33 |
| fabbione | it was just hidden somewhere | 09:33 |
| fabbione | kernel is linking | 09:37 |
| fabbione | ccache populated :) | 09:37 |
| braddr | gcc is buliding | 09:38 |
| braddr | I presume I'll need to grab more bits to build a boot.img file.. | 09:40 |
| === braddr wanders back to google, the fount of knowledge | ||
| fabbione | oh to build that one.. yes | 09:41 |
| fabbione | i can give you the initrd | 09:41 |
| fabbione | all you have to do is to slam it at the bottom of the a.out image | 09:41 |
| braddr | just cat the two together? | 09:42 |
| fabbione | do you have debian/ubuntu on the other linux box? | 09:42 |
| braddr | debian,yes | 09:42 |
| fabbione | apt-get source debian-installer | 09:42 |
| fabbione | look for tftpboot.sh | 09:43 |
| fabbione | that's the script that creates the boot.img | 09:43 |
| braddr | roger | 09:43 |
| fabbione | hmm i can tell you that even if we manage to boot this debug, you won't be able to install | 09:46 |
| fabbione | but i can workaround that with a lot of patience | 09:46 |
| braddr | s'ok.. step one, figure out what's breaking | 09:46 |
| fabbione | yeah | 09:46 |
| braddr | step two.. profit | 09:46 |
| fabbione | :) | 09:46 |
| braddr | that tftpboot.sh script relies on some binaries not part of the installer.. I believe I recognize piggyback from the kernel build, not sure about elf2aout | 09:48 |
| fabbione | elf2out just converts a elf exec to a aout | 09:49 |
| fabbione | i am sure there are sources somewhere | 09:49 |
| fabbione | for sparc they are on sparc-utils pkg | 09:49 |
| === braddr nods | ||
| === braddr will tackle that after getting the crosscompiler built and the linux kernel itself built. :) | ||
| fabbione | i am uploading the image.. | 09:58 |
| fabbione | http://people.ubuntu.com/~fabbione/braddr/ | 10:01 |
| === braddr wgets | ||
| === braddr boot net's. | ||
| braddr | probably should powercycle, but let's see if this gets anything interesting | 10:05 |
| braddr | seems to stall here: | 10:06 |
| braddr | Booting Linux... | 10:06 |
| braddr | mem_init: Calling free_all_bootmem(). | 10:06 |
| fabbione | interesting | 10:07 |
| braddr | any thoughts before I start the 10 minute power cycle bootup? | 10:07 |
| fabbione | it might be just slow??? | 10:08 |
| braddr | been well over a minute now | 10:08 |
| === braddr starts the cycle | ||
| fabbione | ok try again | 10:09 |
| fabbione | i will build one that doesn't trigger that | 10:09 |
| === braddr will need to put a cap on this.. it's after 1am here. | ||
| braddr | I'll go until 2 | 10:10 |
| fabbione | ok | 10:11 |
| fabbione | #ifdef CONFIG_DEBUG_BOOTMEM | 10:11 |
| fabbione | prom_printf("mem_init: Calling free_all_bootmem().\n"); | 10:11 |
| fabbione | #endif | 10:11 |
| fabbione | totalram_pages = num_physpages = free_all_bootmem() - 1; | 10:12 |
| braddr | seems pretty harmless | 10:12 |
| fabbione | checking what that does exactly | 10:13 |
| braddr | considering there's other printf's in the neighborhood, adding one more can't be a problem by itself. | 10:13 |
| fabbione | yeps | 10:15 |
| fabbione | slamming one immediatly after | 10:15 |
| fabbione | to se | 10:15 |
| fabbione | to see if that completes | 10:15 |
| braddr | same stall. | 10:18 |
| === braddr will give it several minutes | ||
| fabbione | i am almost done with the other printk | 10:19 |
| === braddr nods.. that's what I was figuring would be the next boot. :) | ||
| fabbione | it takes a little bit to do things properly | 10:19 |
| fabbione | in terms of change -> track change -> build proper images -> create boot.img -> blabla | 10:20 |
| braddr | screw the properly part. :) | 10:21 |
| fabbione | no i don't.. it's important for me that each bit it's always tested properly... | 10:22 |
| fabbione | we used to hack that way when we were adding the support to the kernel | 10:22 |
| fabbione | but we realized only later that at cleanup time we lost bits here and there | 10:22 |
| === braddr eyes the crosstools build.. died again. | ||
| fabbione | duplicating work etc. | 10:22 |
| === braddr nods. | ||
| braddr | I tend to take a 2 pass approach.. hack and slash until the main bug goes away, then re-do things with better knowledge of the problem from the original source | 10:23 |
| fabbione | yeah but this is more building the image trick to be consistent | 10:26 |
| fabbione | the code is in git.. so it's easy for me to grab the diff and reapply it clean to the main truck | 10:26 |
| fabbione | trunk | 10:26 |
| braddr | sparc64-unknown-linux-gnu-hello-static: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), for GNU/Linux 2.4.3, statically linked, for GNU/Linux 2.4.3, not stripped | 10:27 |
| braddr | yay | 10:27 |
| fabbione | nice | 10:27 |
| fabbione | uploading | 10:31 |
| fabbione | ok it's there | 10:33 |
| fabbione | same url | 10:33 |
| braddr | getting... | 10:33 |
| braddr | for what it's worth, still stalled there. | 10:33 |
| fabbione | #ifdef CONFIG_DEBUG_BOOTMEM | 10:34 |
| fabbione | prom_printf("mem_init: Calling free_all_bootmem().\n"); | 10:34 |
| fabbione | #endif | 10:34 |

| fabbione | #ifdef CONFIG_DEBUG_BOOTMEM | 10:34 |
| fabbione | prom_printf("mem_init: done Calling free_all_bootmem().\n"); | 10:34 |
| fabbione | #endif | 10:34 |
| fabbione | this should tell you if it goes any further | 10:34 |
| fabbione | the stuff that free_all_bootmem calls are woodoo to me | 10:34 |
| === braddr consults his magic eight ball to see what it predicts. | ||
| fabbione | i predict it boots, print my stuff and hangs | 10:34 |
| braddr | that'd be the A answer. | 10:34 |
| fabbione | if it goes further you should see: | 10:35 |
| fabbione | printk("Memory: %uk available (%ldk kernel code, %ldk data, %ldk init) [%016lx,%016lx] \n", | 10:35 |
| braddr | wow.. break from sc isn't getting a prompt. powercycleing | 10:36 |
| braddr | mem_init: done Calling free_all_bootmem(). | 10:43 |
| fabbione | and it hangs... | 10:44 |
| === fabbione sighs | ||
| fabbione | ok let's try without BOOMEM debugging | 10:44 |
| braddr | at least the voodoo off in the boot mem freeing code can be avoided. :) | 10:44 |
| fabbione | yeah | 10:44 |
| fabbione | i should really poweron the SAN to do these builds | 10:51 |
| fabbione | spending ages on I/O on these slow SAS disks | 10:51 |
| braddr | heh | 10:52 |
| ajmitch | hi fabbione | 10:53 |
| fabbione | hi aj | 10:53 |
| fabbione | braddr: almost done... | 10:57 |
| fabbione | got sucked with a customer :/ | 10:57 |
| braddr | no problem.. reading the docs on kbuild to learn how to do cross compiles | 10:57 |
| fabbione | braddr: that's easy ;) | 10:57 |
| fabbione | either edit arch/sparc64/Makefile | 10:58 |
| fabbione | or export hmmm what envvar.. | 10:58 |
| fabbione | HOSTCC and CC | 10:58 |
| fabbione | that should do | 10:58 |
| braddr | and to trigger it as a cross build? | 11:00 |
| fabbione | make ARCH=sparc64 ... | 11:00 |
| fabbione | uploading new image | 11:01 |
| fabbione | this one without DEBUG_BOOTMEM | 11:01 |
| braddr | sweet | 11:01 |
| fabbione | done | 11:04 |
| === braddr wgets the same url | ||
| braddr | Remapping the kernel... done. | 11:09 |
| braddr | Booting Linux... | 11:09 |
| braddr | <stall...> | 11:09 |
| fabbione | how much ram do you have there? | 11:09 |
| braddr | 8G | 11:09 |
| fabbione | ok letme try to boot that image here | 11:10 |
| fabbione | i also have 8GB | 11:11 |
| fabbione | at least we can exclude one thing | 11:12 |
| fabbione | this one stalls for me too | 11:14 |
| fabbione | so it's either scratching all the 8GB of ram very very slowly | 11:14 |
| fabbione | or it is simply broken | 11:14 |
| === braddr votes the latter | ||
| fabbione | i can try removing the ram | 11:14 |
| fabbione | i will let it run for a bit while i get some lunch | 11:14 |
| braddr | one of the boots had to have been sitting there for 10 minutes or so | 11:14 |
| fabbione | and try to come back with an image for tomorrow | 11:14 |
| fabbione | i have no idea how verbose these debugging things are | 11:15 |
| fabbione | i think i will disable all of them and enable one at a time to see what breaks | 11:15 |
| fabbione | it's problably easier | 11:15 |
| fabbione | but it requires a few tons of reboots | 11:15 |
| === braddr nods. | ||
| fabbione | go get some sleep | 11:15 |
| fabbione | i hope to have an image by tomorrow or something | 11:15 |
| braddr | I'm about to try the first kernel build | 11:16 |
| fabbione | ok :) | 11:16 |
| fabbione | but remember that netboot needs to be a.out or it won't work | 11:16 |
| === fabbione -> food | ||
| braddr | thanks for the help.. see ya in 20ish hours | 11:17 |
| fabbione | no problem.. sure | 11:17 |
| fabbione | i should be here :) | 11:17 |
| braddr | well, that failed fast. :) | 11:17 |
| braddr | fyi: make ARCH=sparc64 CROSS_COMPILE=sparc64-unknown-linux-gnu- vmlinux.aout | 11:34 |
| === braddr grogs. | ||
| fabbione | morning | 04:15 |
| braddr | hiya. before I went to sleep, I got a kernel build that worked enough to show the Booting linux... message | 04:18 |
| fabbione | oh nice | 04:18 |
| fabbione | i managed to add a couple of DEBUGGING options from none | 04:19 |
| fabbione | but i had to stop | 04:19 |
| fabbione | i am going to add more now | 04:19 |
| braddr | I didn't get the kernel + initrd image built.. I was more anxious to see the kernel working. I'm gonna eat dinner, watch a bit of tv, then dive back in | 04:19 |
| fabbione | sure | 04:20 |
| fabbione | it will give me a little bit to build another couple of kernels | 04:20 |
| braddr | you're trying to see what debugging options work and which ones cause your own box to die during bootup? | 04:20 |
| fabbione | yeps | 04:21 |
| fabbione | like we discussed yesterday | 04:21 |
| braddr | just checking. They're all 'supposed' to work, I assume.. something buggy with either sparc in general or t2000 specifically, potentially? | 04:21 |
| braddr | I'm still running 2.4 everywhere, so I'm a tad behind the times | 04:22 |
| fabbione | i assume they are all supposed to work individually | 04:22 |
| fabbione | not sure in big combos | 04:22 |
| braddr | I see references to turning some of 'em on in various l-k threads from time to time | 04:22 |
| braddr | I should probably do a build with a .config that matches the installer v 35 build | 04:23 |
| fabbione | yeps | 04:23 |
| fabbione | what sources are you using? | 04:23 |
| fabbione | vanilla or ubuntu? | 04:24 |
| braddr | vanilla 2.6.17-rc5 | 04:24 |
| fabbione | ok | 04:24 |
| fabbione | the config might work | 04:24 |
| fabbione | but a lot of drivers won't be there | 04:24 |
| fabbione | i am booting up now | 04:24 |
| fabbione | can give you a config in 2 minutes or so | 04:25 |
| braddr | for a t2000, a lot of drivers aren't relevant. | 04:25 |
| fabbione | i know | 04:26 |
| fabbione | they are just there | 04:26 |
| braddr | fyi.. a snippit from an email with my sun contact: | 04:30 |
| braddr | > Thank you for your feedback. I have passed it along to the T2000 Try and Buy | 04:30 |
| braddr | > Program people, as it is a new program, we appreciate the constructive | 04:30 |
| braddr | > feedback. As a follow up to your first point, on the T2000 Linux is not | 04:30 |
| braddr | > formally supported (yet) so any efforts Dave is making are best effort. | 04:30 |
| braddr | the 'yet' part I like seeing. | 04:31 |
| fabbione | ehhe | 04:31 |
| braddr | my reply basically said I/we weren't looking for support, just time. | 04:31 |

| braddr | fabbione: hopefully you're still asleep, but for when you wake, not a single oops or other kernel message during the entire install except for during module loading, and there just a bunch of symbol size mismatch messages | 06:50 |
| fabbione | braddr: nice... | 06:50 |
| fabbione | braddr: did you try to boot the SMP kernel? | 06:50 |
| braddr | not yet | 06:50 |
| fabbione | could you please? | 06:51 |
| braddr | just try the default installed smp kernel? | 06:51 |
| fabbione | yeps | 06:51 |
| braddr | ok.. I'll reboot after the rsync of the ubuntu.git tree is done | 06:51 |
| fabbione | thanks | 06:51 |
| braddr | without the debug options, the race or whatever we were hitting is likely to hit, but it'll be interesting regardless. | 06:53 |
| fabbione | it might not | 06:55 |
| braddr | rebooting | 06:57 |
| fabbione | take your time. i am kind of busy anyway | 06:59 |
| braddr | no problem.. just munching on some pizza and catching up on some tv | 06:59 |
| braddr | ncpus probed : 16 | 07:04 |
| braddr | ncpus active : 16 | 07:04 |
| fabbione | :) | 07:06 |
| fabbione | now just play with it :) | 07:06 |
| fabbione | and see how bad it goes | 07:06 |
| braddr | I much prefer reproducable, reliable, regular crashes. | 07:06 |
| fabbione | i might be able to get the config changes in if they are not too heavy | 07:07 |
| fabbione | in terms that we can work around it, but i need to verify how much heavier is the DEBUG_SLAB UP kernel | 07:07 |
| braddr | well, this smp kernel has no config changes.. it's what came from the default install. | 07:07 |
| fabbione | yeps | 07:07 |
| fabbione | that means that it's only with UP kernel the problem | 07:07 |
| braddr | or that the race condition hasn't triggered | 07:08 |
| fabbione | probably | 07:08 |
| fabbione | as i said.. play with it and see if you notice anything strange | 07:08 |
| fabbione | i have 24h to upload a kernel | 07:08 |
| fabbione | after that it will be a matter of custom installers | 07:08 |
| braddr | I'll have it do a few make -j32 kernel compiles.. always good for a stress test | 07:09 |
| fabbione | -j512 is good too | 07:09 |
| fabbione | don't be shy | 07:09 |
| fabbione | the machine won't yell at you | 07:09 |
| braddr | the disk might.. it's not one of the snappiest ever created. | 07:10 |
| fabbione | don't worry about that | 07:10 |
| fabbione | trust me :) | 07:10 |
| fabbione | davem didn't finf bugs on the kernel doing -j32 | 07:10 |
| fabbione | i did when pushing to the edges of -j4096 | 07:10 |
| braddr | right.. make -j <nothing> it is. | 07:10 |
| fabbione | yeah | 07:10 |
| fabbione | ok while you play.. i need to get ready to fly to London | 07:11 |
| braddr | if it's gonna be stressed, let's throw it all at her | 07:11 |
| braddr | whee | 07:11 |
| fabbione | i have an airplane to catch in a few hours | 07:11 |
| fabbione | stress her as much as you can | 07:11 |
| fabbione | the more the better | 07:11 |
| braddr | while /bin/true; do make clean; make -j; done | 07:12 |
| fabbione | :) | 07:15 |
| braddr | ouch.. aboutu 1.5G into swap, about 1200 processes all fighting for some time | 07:20 |
| fabbione | that's o | 07:20 |
| fabbione | k | 07:20 |
| fabbione | don't worry | 07:20 |
| braddr | oh, I know.. as long as I don't run outta swap it's all good | 07:20 |
| fabbione | you won't | 07:21 |
| fabbione | make -j will make sure not to go over machine resources | 07:21 |
| fabbione | it's done on purpose | 07:21 |
| braddr | yeah, looks like it's over the parallelism hump anyway | 07:21 |
| fabbione | ok gotta go for a bit now | 07:22 |
| fabbione | ttyl | 07:22 |
| braddr | have fun in London | 07:22 |
| fabbione | nah still need to prepare the bag, shower and close here ;) | 07:22 |
| fabbione | another 2/3 hours | 07:22 |
| fabbione | just need to get started :D | 07:22 |
| braddr | interesting that 2 make processes seem to be consuming 2 of the cores full time | 07:26 |
| braddr | ooh.. an oops, and file-max limit reached | 07:34 |
| fabbione | max file is a known bug upstream | 07:37 |
| fabbione | log the OOPS | 07:37 |
| braddr | already done | 07:37 |
| fabbione | the file-max is due to SLAB not releasing cleared fd fast enough | 07:37 |
| braddr | the oops is in one of the make's that's spinning.. which makes some sense. | 07:38 |
| braddr | wait, no it's not. | 07:38 |
| braddr | fun.. the two make's aren't kill -9able | 07:42 |
| fabbione | add all to the logs :) | 07:44 |
| fabbione | oh hold on | 07:44 |
| fabbione | once you hit the file-max you need to reboot | 07:44 |
| braddr | way ahead of you | 07:44 |
| fabbione | there is no proper way to recover from that | 07:45 |
| braddr | the oops came before the first file-max | 07:45 |
| ajmitch | evening | 07:46 |
| braddr | hiya aj | 07:46 |
| ajmitch | sounds like you're stressing the box nicely :) | 07:47 |
| braddr | just following suggestions | 07:47 |
| === ajmitch is still waiting to hear what gets sorted out with this one | ||
| braddr | me too | 07:47 |
| braddr | but progress has definitly been made | 07:47 |
| === braddr reboots | ||
| fabbione | braddr: what's the url for the log again? | 08:39 |
| braddr | http://www.puremagic.com/~braddr/t2000/boots.txt | 08:39 |
| fabbione | thanks | 08:39 |
| braddr | drop the file for a blog + a list of all the past files (from a month or so ago) | 08:40 |
| fabbione | ? | 08:40 |
| braddr | http://www.puremagic.com/~braddr/t2000/ | 08:40 |
| fabbione | oh ok :) | 08:41 |
| braddr | drivers/block/aoe/aoemain.o -- there's an Age of Empires game embedded in the kernel? :P | 08:49 |
| fabbione | hahah | 08:49 |
| fabbione | -> London | 09:48 |
| fabbione | later | 09:48 |
