[13:20] * henrix -> (late) lunch [13:20] rtg: Hey [13:21] hmm? [13:21] * Prf_Jakob Bornecrantz [13:21] vmwgfx guy [13:21] does it work for you ? [13:21] I haven't test it actually [13:22] But I can do that. [13:22] I'm wondering if you will cherry pick those to patch and maybe even the dumb_fb patch? [13:23] Prf_Jakob, the first patch is in Ubuntu-3.5.0-14.15, and is coming in Precise. [13:23] Ah ok good [13:23] I'm reluctant to pick the FB patch since it does represent a more radical change [13:24] Prf_Jakob, the bug reporter did indicate that the minimal patch solved his issues [13:24] the xf86-video-vmware packages install a modprobe rule that does the same. [13:25] Prf_Jakob, I'm fine with leaving it up to user space to do that [13:25] Ok [13:25] Prf_Jakob, the first patch is in Precise Ubuntu-3.2.0-31.50 (likely still in -proposed) [13:26] k thanks === Kiall is now known as zz_Kiall [13:52] folks, I would really appreciate a look at bug 1049395, we have had 5 failures on 7 runs on it [13:52] 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 === jsalisbury changed the topic of #ubuntu-kernel to: Home: https://wiki.ubuntu.com/Kernel/ || Ubuntu Kernel Team Meeting - Tues September 18th, 2012 - 17:00 UTC || If you have a question just ask, and do wait around for an answer! === zz_Kiall is now known as Kiall [14:00] 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 [14:02] hggdh: you could try 2.6.38-15.66 for comparison [14:02] ogasawara, can somebody bump the ABI in linux-meta-lowlatency? [14:02] quantal [14:08] 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. [14:10] yeah, maybe rebasing. I see in NBS: [14:10] linux-headers-3.5.0-13 [14:10] linux-headers-3.5.0-13-lowlatency universe amd64 i386 [14:12] rtg: ^^ think you could rebase apw's lowlatency kernel and upload to universe today? I've gotta bail here in a second. [14:13] ogasawara, can do [14:13] rtg: thanks [14:14] * ogasawara heads downtown [14:14] bjf: OK. I will tag it qa-testing-passed, but I still do not like the number of failures [14:14] hggdh: can you test the previous kernel version? [14:18] bjf: I can hack around it, yes, doing it manually [14:23] 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 ? [14:24] bjf: I will first re-run it to have a full repeat, then I will retest the current -updates kernel [14:39] rtg, no, all 3 of my test systems are servers and i've not tried that here at home, i could pretty easily though [14:40] 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. [16:37] hey, bug 1049650 is annoying [16:37] Launchpad bug 1049650 in linux "Regression: "Undefined video mode" with 3.5.0-14.16" [Medium,Incomplete] https://launchpad.net/bugs/1049650 [16:42] sforshee, did your gmux crack do this ? ^^ [16:42] rtg, I seriously doubt it. It's not even an apple machine. [16:43] sforshee, its about the only think even vaguely related to video [16:43] rtg, apple-gmux shouldn't load unless the right hid appears in the ACPI tables, and it should only be there on apple machines [16:44] sforshee, right [16:46] Curious if anyone in Ubuntu is looking at the pstore infrastructure (using it to capture oops logs, etc)? [16:47] jstultz, I think cking had some interest in it [16:47] rtg: cool [16:48] 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] not exercised pstore yet though [16:49] 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] 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.. [16:50] cking: also there's been recent work to get ftrace output captured by pstore [16:50] jstultz, that's a nice debugging feature. could have done with that several years ago working on ARM devices. [16:51] 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. [16:52] jstultz, when are these changes going to land in mainline? [16:52] cking: 3.6 [16:53] cking: they should all be there already [16:53] (the ftrace bits may still be pending for 3.7.. ) [16:53] ok, so Quantal+1 now [16:53] cking: yep... [16:54] 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] cking: the hope is that pstore will abstract some of the uefi vs arm differences [16:54] cking: not necessarily.. i think you can size the memory space.. [16:55] cking: it just helps to get exactly what functions were called right before an oops [16:55] jstultz, indeed, that would be a big win [16:55] cking: the arm only aspect of the persistent-ram part of pstore is really only hardware based.. [16:56] most x86 hardware clears ram state over warm reset... [16:56] ok [16:56] if an architecture doesn't clear ram, then it should be usable. [16:56] indeed, pity about x86 PCs clearing memory really. [16:57] and we can still try to log to ram regardless, but we just won't find anything on reset [16:57] (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 [16:58] cking: anyway, just wanted to raise awareness... thanks for listening! :) [16:58] cking: feel free to ping me or cbou on #linaro-kernel if you have further questions [16:58] jstultz, I appreciate you letting me know, much appreciated :-) [16:58] ack [17:35] * rtg -> lunch [17:57] * henrix -> EOD === henrix is now known as henrix_ [19:17] arges, flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc extd_apicid amd_dcm aperfmperf pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 popcnt aes xsave avx f16c lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs xop skinit wdt lwp fma4 tce nodeid [19:17] _msr tbm topoext perfctr_core arat cpb hw_pstate npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold bmi1 [19:17] rtg, yup it has avx and fma4 [19:19] rtg, https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/956051 [19:19] Launchpad bug 956051 in eglibc "libc6 crash while running 'xm'" [High,Confirmed] === cmagina-lunch is now known as cmagina === emma is now known as em [20:23] * rtg -> EOD
