| * rtg upgrades his laptop to quantal.... | 12:13 | |
| * henrix -> (late) lunch | 13:20 | |
| Prf_Jakob | rtg: Hey | 13:20 |
| rtg | hmm? | 13:21 |
| * Prf_Jakob Bornecrantz | 13:21 | |
| Prf_Jakob | vmwgfx guy | 13:21 |
| rtg | does it work for you ? | 13:21 |
| Prf_Jakob | I haven't test it actually | 13:21 |
| Prf_Jakob | But I can do that. | 13:22 |
| Prf_Jakob | I'm wondering if you will cherry pick those to patch and maybe even the dumb_fb patch? | 13:22 |
| rtg | Prf_Jakob, the first patch is in Ubuntu-3.5.0-14.15, and is coming in Precise. | 13:23 |
| Prf_Jakob | Ah ok good | 13:23 |
| rtg | I'm reluctant to pick the FB patch since it does represent a more radical change | 13:23 |
| rtg | Prf_Jakob, the bug reporter did indicate that the minimal patch solved his issues | 13:24 |
| Prf_Jakob | the xf86-video-vmware packages install a modprobe rule that does the same. | 13:24 |
| rtg | Prf_Jakob, I'm fine with leaving it up to user space to do that | 13:25 |
| Prf_Jakob | Ok | 13:25 |
| rtg | Prf_Jakob, the first patch is in Precise Ubuntu-3.2.0-31.50 (likely still in -proposed) | 13:25 |
| Prf_Jakob | k thanks | 13:26 |

| hggdh | folks, I would really appreciate a look at bug 1049395, we have had 5 failures on 7 runs on it | 13:52 |
| ubot2 | Launchpad bug 1049395 in linux "ext4: kernel BUG at /build/buildd/linux-2.6.38/fs/buffer.c:2900!" [Undecided,Confirmed] https://launchpad.net/bugs/1049395 | 13:52 |

| bjf | hggdh, i'll look but as i was explaining yesterday, i've seen this occasionally myself and of the 13 commits that have gone into natty in the last two kernel versions, _none_ are against ext4. they are mostly networking or ecryptfs | 14:00 |
| bjf | hggdh: you could try 2.6.38-15.66 for comparison | 14:02 |
| doko | ogasawara, can somebody bump the ABI in linux-meta-lowlatency? | 14:02 |
| doko | quantal | 14:02 |
| ogasawara | doko: I don't see it needing an ABI bump yet for quantal, ie it's at -13. am I missing something? I do see it needs rebasing to -14 though. | 14:08 |
| doko | yeah, maybe rebasing. I see in NBS: | 14:10 |
| doko | linux-headers-3.5.0-13 | 14:10 |
| doko | linux-headers-3.5.0-13-lowlatencyuniverseamd64 i386 | 14:10 |
| ogasawara | rtg: ^^ think you could rebase apw's lowlatency kernel and upload to universe today? I've gotta bail here in a second. | 14:12 |
| rtg | ogasawara, can do | 14:13 |
| ogasawara | rtg: thanks | 14:13 |
| * ogasawara heads downtown | 14:14 | |
| hggdh | bjf: OK. I will tag it qa-testing-passed, but I still do not like the number of failures | 14:14 |
| bjf | hggdh: can you test the previous kernel version? | 14:14 |
| hggdh | bjf: I can hack around it, yes, doing it manually | 14:18 |
| rtg | bjf, have you upgraded to Quantal on a machine that referenced the X packages in https://launchpad.net/~ubuntu-x-swat/+archive/q-lts-backport ? | 14:23 |
| hggdh | bjf: I will first re-run it to have a full repeat, then I will retest the current -updates kernel | 14:24 |
| bjf | rtg, no, all 3 of my test systems are servers and i've not tried that here at home, i could pretty easily though | 14:39 |
| rtg | bjf, If you've got a VM that would be handy. it seems some of the packages don't get updated. I'm suspecting some version issues. | 14:40 |
| jbicha | hey, bug 1049650 is annoying | 16:37 |
| ubot2 | Launchpad bug 1049650 in linux "Regression: "Undefined video mode" with 3.5.0-14.16" [Medium,Incomplete] https://launchpad.net/bugs/1049650 | 16:37 |
| rtg | sforshee, did your gmux crack do this ? ^^ | 16:42 |
| sforshee | rtg, I seriously doubt it. It's not even an apple machine. | 16:42 |
| rtg | sforshee, its about the only think even vaguely related to video | 16:43 |
| sforshee | rtg, apple-gmux shouldn't load unless the right hid appears in the ACPI tables, and it should only be there on apple machines | 16:43 |
| rtg | sforshee, right | 16:44 |
| jstultz | Curious if anyone in Ubuntu is looking at the pstore infrastructure (using it to capture oops logs, etc)? | 16:46 |
| rtg | jstultz, I think cking had some interest in it | 16:47 |
| jstultz | rtg: cool | 16:47 |
| cking | well, my UEFI boxes with Quantal do save kernel log messages to the UEFI variable space, so that's a debugging win for me | 16:48 |
| cking | not exercised pstore yet though | 16:48 |
| jstultz | cking: cool :) part of why I ask, is that Anton Vorontsov at linaro has been working on getting some of the android features merged into pstore | 16:49 |
| jstultz | cking: so for instance on arm, it can use persistent-ram (doesn't clear on warm reset) instead of bios provided flash to store dmesg logs.. | 16:49 |
| jstultz | cking: also there's been recent work to get ftrace output captured by pstore | 16:50 |
| cking | jstultz, that's a nice debugging feature. could have done with that several years ago working on ARM devices. | 16:50 |
| jstultz | cking: but i just wanted to make sure these features were promoted enough so folks who might be able to integrate them know they're there. | 16:51 |
| cking | jstultz, when are these changes going to land in mainline? | 16:52 |
| jstultz | cking: 3.6 | 16:52 |
| jstultz | cking: they should all be there already | 16:53 |
| jstultz | (the ftrace bits may still be pending for 3.7.. ) | 16:53 |
| cking | ok, so Quantal+1 now | 16:53 |
| jstultz | cking: yep... | 16:53 |
| cking | jstultz, are these just ARM only features? the ftrace in pstore sounds like a cool idea, but probably uses up lots of memory | 16:54 |
| jstultz | cking: the hope is that pstore will abstract some of the uefi vs arm differences | 16:54 |
| jstultz | cking: not necessarily.. i think you can size the memory space.. | 16:54 |
| jstultz | cking: it just helps to get exactly what functions were called right before an oops | 16:55 |
| cking | jstultz, indeed, that would be a big win | 16:55 |
| jstultz | cking: the arm only aspect of the persistent-ram part of pstore is really only hardware based.. | 16:55 |
| jstultz | most x86 hardware clears ram state over warm reset... | 16:56 |
| cking | ok | 16:56 |
| jstultz | if an architecture doesn't clear ram, then it should be usable. | 16:56 |
| cking | indeed, pity about x86 PCs clearing memory really. | 16:56 |
| jstultz | and we can still try to log to ram regardless, but we just won't find anything on reset | 16:57 |
| jstultz | (although that could be wasteful.. but atleast provides a way to avoid configuration twiddling) | 16:57 |
| * cking adds it to his list of things to examine and test on suitable kit | 16:57 | |
| jstultz | cking: anyway, just wanted to raise awareness... thanks for listening! :) | 16:58 |
| jstultz | cking: feel free to ping me or cbou on #linaro-kernel if you have further questions | 16:58 |
| cking | jstultz, I appreciate you letting me know, much appreciated :-) | 16:58 |
| cking | ack | 16:58 |
