| fabbione | hey tmarble | 04:03 |
|---|---|---|
| tmarble | fabbione: ciao | 04:03 |
| tmarble | so are you, or David, lacking hardware to find this bug? | 04:04 |
| tmarble | not that I can do anything about it... but I thought i'd ask | 04:04 |
| fabbione | what bug? | 04:06 |
| fabbione | it's not like we have just one :) | 04:07 |
| fabbione | let me rephrase that | 04:07 |
| fabbione | we have no bugs.. | 04:07 |
| fabbione | the hw just doesn't work | 04:07 |
| fabbione | :P | 04:07 |
| tmarble | ah. so you're saying it's my problem ;-) | 04:12 |
| fabbione | eheh | 04:13 |
| fabbione | no seriously.. i have been hacking like mad today | 04:13 |
| fabbione | what bug are you talking about? | 04:13 |
| tmarble | BUG: soft lockup detected on CPU#2! | 04:14 |
| fabbione | i already fixed that | 04:15 |
| fabbione | it's pushed in git but it will take a few days to be uploaded | 04:15 |
| fabbione | and i found another bug in the reboot code for the kernel that get trapped by the HV and generate a poweroff error | 04:15 |
| tmarble | hmmm yes.. having both those fixes will be nice | 04:16 |
| fabbione | i thought that the latter was caused by the former, but i have been proven wrong | 04:18 |
| tmarble | for the purpose of debugging, would it make sense to package up linux-image-2.6.17-10-sparc64-smp with these fixes such that I can try them? | 04:44 |
| tmarble | i.e. before it becomes a 2.6.17.n release? | 04:44 |
| fabbione | i already tested it, but i can upload an image if you want | 04:51 |
| tmarble | as I only have this box for little over a week I'd like to get going with it -- if it's not too much trouble | 04:52 |
| tmarble | there also would be enormous value in confirming the effectiveness of the fix | 04:53 |
| tmarble | if, for some reason, the fix(es) are not sufficient I assume it is better to know that early, right? | 04:53 |
| tmarble | So, for example, I don't know if it's possible for me to take the recent boot.img from yesterday at http://archive.ubuntu.com/ubuntu/dists/edgy/main/installer-sparc/current/images/sparc64/netboot/2.6/ | 04:54 |
| tmarble | and then point at a non-production mirror (if you prefer) | 04:54 |
| tmarble | then we wouldn't have to wait the 6 hours for ubuntu dinstall, right? | 04:55 |
| fabbione | halt.. | 04:55 |
| fabbione | you are confusing 2 things here | 04:55 |
| fabbione | one is the d-i error you saw | 04:55 |
| fabbione | that has been addressed yesterday | 04:56 |
| tmarble | k | 04:56 |
| fabbione | the new image will work just fine | 04:56 |
| fabbione | but there might be instability in the mirrors soon | 04:56 |
| fabbione | new image will be default in a couple of hours | 04:56 |
| tmarble | will it, indeed, be linux-image-2.6.17-10-sparc64-smp ? | 04:56 |
| fabbione | yes, but that image doesn't contain the fix for the CPU lockups yet | 04:57 |
| fabbione | so what i suggest to do is: | 04:57 |
| tmarble | right -- I confirm the d-i bug is fixed -- install completed nicely | 04:57 |
| fabbione | wait tomorrow or thursday for the new image | 04:57 |
| fabbione | install | 04:57 |
| fabbione | you will see also a login prompt on the console (that was broken when you did the first install) | 04:58 |
| fabbione | and then we can install the new kernel with the fix | 04:58 |
| fabbione | if the fix will not hit archive before that | 04:58 |
| tmarble | ah, so you are saying that linux-image-2.6.17-11-sparc64-smp *will* include the CPU lockup fix? | 04:58 |
| fabbione | it can also be -10- with a version bump | 04:58 |
| tmarble | ah - ok | 04:59 |
| fabbione | -10- or -9- indicates the ABI version of the kernel | 04:59 |
| tmarble | right, my bad | 04:59 |
| fabbione | nah that's ok | 04:59 |
| fabbione | a lot of people don't grok that easily | 04:59 |
| tmarble | I actually do understand upstream vs. debian versions -- just not facile with these package names yet | 04:59 |
| fabbione | yeah | 05:00 |
| fabbione | kernel is special in this regard | 05:00 |
| tmarble | but, your point is, by tomorrow or thursday we will have a kernel with the CPU lockup fix, right? | 05:00 |
| fabbione | no, my point is that by tomorrow or thursday you will get an image that will install and take you to a console | 05:03 |
| fabbione | the reason why you didn't get a console was because of a bug in the installer that was fixed today | 05:03 |
| tmarble | ok | 05:03 |
| fabbione | the kernel with the CPU lock fixed is on my niagara and i can give you a copy | 05:04 |
| tmarble | but am I still going to trip over CPU lockup? | 05:04 |
| fabbione | yes right | 05:04 |
| fabbione | that's not a big deal | 05:04 |
| tmarble | ah - -then I install manually from the console? | 05:04 |
| fabbione | exactly | 05:04 |
| fabbione | i can also explain to you how to fix your actual install | 05:04 |
| tmarble | are you going to give me a .deb | 05:04 |
| fabbione | and get a console | 05:04 |
| fabbione | yes i will give you a deb | 05:04 |
| tmarble | easy enough | 05:04 |
| fabbione | if you are bored.. netboot the machine with the installer | 05:04 |
| fabbione | get to the partitioner and <go back> | 05:05 |
| fabbione | get to the main menu | 05:05 |
| tmarble | choose ash | 05:05 |
| tmarble | ? | 05:05 |
| fabbione | "exit to a shell" or something similar | 05:05 |
| fabbione | mount your root somewhere | 05:05 |
| tmarble | it's already on /target isn't it? | 05:05 |
| fabbione | it's on target if you install | 05:05 |
| fabbione | but since you already installed, might as well fix the install | 05:06 |
| tmarble | ah -- ok | 05:06 |
| fabbione | so if you get to the partitioner, before reformatting anything | 05:06 |
| fabbione | get to the shell as i told you | 05:06 |
| fabbione | mount / somewhere | 05:06 |
| fabbione | in /etc/events.d | 05:06 |
| fabbione | add a file called ttyS0 | 05:06 |
| fabbione | and slam this in it: | 05:06 |
| fabbione | start on runlevel-2 | 05:07 |
| fabbione | start on runlevel-3 | 05:07 |
| fabbione | start on runlevel-4 | 05:07 |
| fabbione | start on runlevel-5 | 05:07 |
| fabbione | stop on shutdown | 05:07 |
| fabbione | respawn /sbin/getty -L ttyS0 9600 vt102 | 05:07 |
| fabbione | (actually it's /etc/event.d) | 05:07 |
| fabbione | reboot from there | 05:07 |
| tmarble | I assume this is under my mount -- not the installer real / , correct? | 05:07 |
| fabbione | yes right | 05:07 |
| fabbione | under the mount | 05:07 |
| tmarble | k | 05:07 |
| fabbione | that will give you console access | 05:07 |
| tmarble | ah.. good | 05:07 |
| fabbione | now i need to finish a couple of silo fixes | 05:07 |
| tmarble | then I can install your deb from that | 05:07 |
| tmarble | ok | 05:07 |
| tmarble | one more, different question please | 05:08 |
| fabbione | and i will upload the image on people.ubuntu.com/~fabbione/tmarble | 05:08 |
| tmarble | k | 05:08 |
| tmarble | my colleage wants to boot (from OBP) to a given partition (in his case, parition 4) | 05:08 |
| tmarble | I asked him to try this: | 05:08 |
| tmarble | ok boot /pci@780/pci@0/pci@9/scsi@0/disk@0,0:d | 05:09 |
| tmarble | BUT, it said "file is not executable" | 05:09 |
| tmarble | is there some other way to do this? | 05:09 |
| fabbione | did he install silo in the partition? or in the MBR? | 05:09 |
| tmarble | i'll ask, hold please | 05:10 |
| fabbione | the installer by default uses the MBR iirc | 05:11 |
| tmarble | ok... | 05:11 |
| fabbione | to install on the partition you need to do it manually | 05:11 |
| fabbione | IIRC with silo -f -t | 05:11 |
| fabbione | but he needs to check on the manpage | 05:11 |
| fabbione | i really don't remember | 05:11 |
| tmarble | I have to read more on silo, but is there any reason I can't add an entry in silo to jump to a partition (that happens to be running Solaris)? | 05:11 |
| tmarble | k | 05:11 |
| fabbione | yes you can add an entry to silo | 05:11 |
| tmarble | any thoughts about supporting grub? | 05:12 |
| fabbione | there are some people working on grub2 | 05:12 |
| tmarble | supposedly grub understands Sun VTOC | 05:12 |
| fabbione | but i have no idea about the status | 05:12 |
| tmarble | k | 05:12 |
| tmarble | nikolay is not responding... please go ahead to work on your silo fixes... | 05:13 |
| tmarble | thanks for your help! let me know when you have a deb for me | 05:13 |
| fabbione | it won't take long for the deb | 05:14 |
| fabbione | i need to build the kernrel but it takes only a few minutes on Niagara :) | 05:14 |
| tmarble | ok... i'll try to get the console thing fixed now | 05:14 |
| fabbione | btw.. tell Nikolay that i didn't forget about his gcc/linking issue | 05:15 |
| fabbione | i just had no time to work on it | 05:15 |
| fabbione | silo booting is beta blocker | 05:15 |
| tmarble | yeah -- I have promised to file a bug on that (and he has another kernel NFS bug I need to file too) | 05:15 |
| fabbione | /usr/bin/make -j512 EXTRAVERSION=-10-sparc64-smp ARCH=sparc64 \ | 05:46 |
| fabbione | image | 05:46 |
| fabbione | almost there :) | 05:46 |
| fabbione | that -j512 makes things go *slightly* faster :) | 05:46 |
| tmarble | I had trouble on install components -- skipping to detect disks | 06:01 |
| fabbione | they are changing the kernel bits in the archive as we speak | 06:03 |
| tmarble | i figured that... jumped to ash too early .. /dev/sdb was not known | 06:03 |
| fabbione | eheh | 06:03 |
| tmarble | mounted | 06:04 |
| fabbione | nice | 06:05 |
| fabbione | kernel is almost ready | 06:05 |
| fabbione | testing one more fix | 06:05 |
| tmarble | don't have /etc/event.d | 06:05 |
| tmarble | shall i mkdir | 06:05 |
| fabbione | it has to be there | 06:07 |
| fabbione | are you chrooted in /target or using real /etc ? | 06:07 |
| tmarble | does this look right (sorry for the flood): | 06:07 |
| tmarble | /mnt/event.d # pwd | 06:07 |
| tmarble | /mnt/etc/event.d | 06:07 |
| tmarble | /mnt/event.d # cat ttyS0 | 06:07 |

| tmarble | /mnt/event.d # | 06:08 |
| fabbione | /etc/event.d ? | 06:08 |
| tmarble | that's ash that is confused -- hence the pwd | 06:08 |
| fabbione | /mnt/etc/event.d | 06:08 |
| fabbione | that directory has to be there | 06:09 |
| fabbione | what's in there? | 06:09 |
| fabbione | is it empty? | 06:09 |

| fabbione | no | 06:12 |
| fabbione | it's all wrong | 06:12 |
| fabbione | do you have /etc ? | 06:12 |
| fabbione | or did you mount /boot by mistake? | 06:12 |
| tmarble | perhaps.. let me try again | 06:13 |

| tmarble | Correct? | 06:18 |
| fabbione | looks much better now :) | 06:20 |
| tmarble | ok | 06:20 |
| tmarble | now umount and reboot? | 06:20 |
| fabbione | yeps | 06:20 |
| tmarble | k | 06:20 |
| fabbione | i am booting the test kernel for you | 06:21 |
| === tmarble steps away to get lunch before conference calls begin in 30 min | ||
| === tmarble back | ||
| fabbione | tmarble: you eat too fast | 06:37 |
| tmarble | no.. i just got the food -- will eat during the ConCall :-( | 06:38 |
| fabbione | oh | 06:38 |
| fabbione | i am reliefed i am not the only one :) | 06:38 |
| tmarble | i'm booting into solaris on sysdisk0 on reboots .... | 06:40 |
| tmarble | i thought I could set this in OBP: | 06:40 |
| tmarble | setenv auto-boot false | 06:40 |
| tmarble | but it doesn't like that/ | 06:40 |
| tmarble | {7} ok setenv auto-boot? false | 06:43 |
| tmarble | auto-boot? = false | 06:43 |
| tmarble | there is already one there now? | 06:45 |
| fabbione | i didn't notice | 06:45 |
| fabbione | yeah but i am testing one with an extra fix | 06:45 |
| tmarble | ah | 06:45 |
| fabbione | that one is useable | 06:45 |
| tmarble | OK ...last time it stopped here, I pressed <return> and it continued...... is it normal to stop here? | 06:47 |
| tmarble | Rebooting with command: boot disk1 | 06:47 |
| tmarble | Boot device: /pci@780/pci@0/pci@9/scsi@0/disk@1 File and args: | 06:47 |
| tmarble | SILO Version 1.4.12 | 06:47 |
| tmarble | boot: boot: | 06:47 |
| fabbione | it's normal.. but there is a timeout | 06:48 |
| tmarble | just press return now, then? | 06:48 |
| fabbione | it gives you time to chose the kernel or otherwise it will go by itself | 06:48 |
| fabbione | yeah | 06:48 |
| tmarble | Ubuntu edgy (development branch) blade220 ttyS0 | 06:50 |

| tmarble | root@blade220:~# | 06:51 |
| tmarble | I'm ready | 06:51 |
| fabbione | yeah i am doing the last boot.. only a few minutes (hopefully) | 06:51 |
| fabbione | but you can start using that one to avoid CPU lockups | 06:52 |
| tmarble | no worries -- now I can at least repair this system | 06:52 |
| tmarble | i'll wait | 06:52 |
| fabbione | uploading the new version now | 07:01 |
| tmarble | cool | 07:01 |
| fabbione | tmarble: can you please get somebody to look at https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/62485 ? | 07:10 |
| fabbione | it would be enough to know what the hell that message from the HV means | 07:10 |
| tmarble | hold on | 07:10 |
| fabbione | note that it doesn't happen with the old dapper kernel | 07:11 |
| fabbione | only on edgy | 07:11 |
| fabbione | and the kernel is on people | 07:11 |
| tmarble | So, I added the deb.... | 07:26 |
| tmarble | it looks like silo is set for | 07:26 |
| tmarble | image=/vmlinuz | 07:26 |
| tmarble | and the link was updated | 07:27 |
| tmarble | vmlinuz -> boot/vmlinuz-2.6.17-10-sparc64-smp | 07:27 |
| tmarble | so, just reboot, right? | 07:27 |
| fabbione | yes but make sure you have vmlinux.old pointing to the old kernel | 07:28 |
| fabbione | just in case | 07:28 |
| fabbione | after that.. reboot | 07:29 |
| tmarble | it does | 07:29 |
| tmarble | so , in case of trouble do.... boot: vmlinux.old | 07:29 |
| fabbione | LinuxOLD | 07:29 |
| fabbione | there is an alias set in silo.conf | 07:29 |
| tmarble | right.. just saw that in silo.conf | 07:29 |
| fabbione | at silo: you can tab | 07:29 |
| fabbione | and see what images are available | 07:29 |
| tmarble | ok | 07:30 |
| fabbione | last reboot and i am off for today | 07:31 |
| tmarble | ok | 07:31 |
| fabbione | 15 hours in the day.. i am dead tired | 07:31 |
| tmarble | i can't understand??? | 07:31 |
| fabbione | 15 hours of work today.. i am dead tired | 07:32 |
| tmarble | thanks so much -- I'm rebooting now | 07:32 |
| fabbione | no problem at all | 07:32 |
| fabbione | you might get that HV error | 07:32 |
| fabbione | as i did show you in the bug | 07:32 |
| fabbione | the machine might poweroff | 07:32 |
| fabbione | i should also get some new OBP for my T2000 | 07:32 |
| fabbione | but that can wait tomorrow | 07:33 |
| tmarble | yes you should | 07:33 |
| fabbione | tmarble: can you send me a link with the latest crack? | 07:33 |
| tmarble | what should i do about the HV bug? | 07:33 |
| tmarble | sure | 07:33 |
| fabbione | i need to know what that error means | 07:33 |
| tmarble | it was in an e-mail i sent you | 07:33 |
| tmarble | ok | 07:33 |
| fabbione | checking in the emails | 07:34 |
| fabbione | ah no | 07:34 |
| fabbione | you gave it to me here on IRC | 07:34 |
| fabbione | and i did install that update | 07:34 |
| fabbione | i need to check fi there are new ones | 07:34 |
| tmarble | 123482-02 | 07:35 |
| fabbione | hmm | 07:36 |
| fabbione | noi can't find it | 07:36 |
| fabbione | in my url list i mean | 07:36 |
| tmarble | ok hold on | 07:37 |
| fabbione | i have it now | 07:37 |
| fabbione | it's years i don't do sysadm on solaris, but i still remember how to search on sun.com :) | 07:38 |
| fabbione | http://sunsolve.sun.com/search/document.do?assetkey=1-21-123482-02-1 | 07:38 |
| tmarble | right | 07:38 |
| fabbione | Wed Sep 13 12:26:54 MDT 2006 | 07:38 |
| fabbione | 6437802 JBI Fatal HV error should not happen when I/O protection is on | 07:40 |
| fabbione | that smells like it | 07:40 |
| tmarble | had to powercycle my box... still waiting | 07:41 |
| fabbione | yeah i told you | 07:41 |
| fabbione | it's annoying | 07:41 |
| fabbione | anyway i am off | 07:41 |
| fabbione | the kernel will boot fine | 07:41 |
