=== hggdh_AFK is now known as hggdh [02:49] woohoo, nvidia-current worked this time [02:55] apw: say, i'm hoping to do a lxc irc meeting in a few weeks to discuss direction with userns. The first 20 minutes would be an overview. Would you or anyone from kernel team want to listen in on that part?

[14:45] jsalisbury: yea i'm doing that now... getting a backtrace and if we are really lucky ill have a vmcore as well [14:46] arges, cool. I recall a similar bug reported in the past few days. I don't remember off had if it was for Precise. I'll go an look [14:48] arges, it could be bug 1097396 that you are hitting. [14:48] Launchpad bug 1097396 in linux (Ubuntu) "Unplugging USB Headset causes Kernel Panic" [High,Incomplete] https://launchpad.net/bugs/1097396 [14:48] jsalisbury: easily reproducible at this point.. tempted to try my raring laptop. but don't want to loose IRC [14:49] jsalisbury: cool looks like this is also precise [14:49] arges, yeah, I started a bisect, but waiting for testing feedback. [14:49] arges, can you try the latest 3.2 kernel? It's 3.2.37 now [14:49] jsalisbury: let me compare notes [14:50] jsalisbury: to see if i'm hitting the same thing [14:50] arges, that bug is fixed in mainline [14:50] arges, and raring [14:52] jsalisbury: we have a winner snd_complete_urb [14:52] jsalisbury: same backtrace here [14:52] arges, cool [14:52] downloading and testing [14:53] arges, yeah, it could be fixed in .37 since it's fixed in the 3.7 and 3.8 kernels. [15:00] jsalisbury: ok tried that kernel still paniced [15:01] arges, ok. Maybe a reverse bisect is needed [15:01] hmm now kdump wants to work :) [15:02] heh [15:02] cking, does the firmware on your x230 have an object named BRTW in the EC namespace that is returned by _BCL? [15:03] arges, i haven't done any research upstream on that bug yet. That's another approach in addition to a reverse bisect [15:04] jsalisbury: if you want to start the bisect, i could look at the backtrace a bit and see if I can get anything by looking and blaming [15:04] arges, I believe v3.7 final did not have the bug. Maybe try v3.6 final? [15:04] jsalisbury: ok that's a bit easier... machine is still taking a dump [15:04] that sounds bad [15:05] arges, sure. I can't reproduce the bug here, but I'll update bug 1097396 and work with Tony [15:05] Launchpad bug 1097396 in linux (Ubuntu Precise) "Unplugging USB Headset causes Kernel Panic" [High,Triaged] https://launchpad.net/bugs/1097396 [15:07] jsalisbury:well i'lll test 3.6 first [15:07] arges, cool [15:07] jsalisbury: and i can do the bisect [15:07] arges, great. can you also update that bug as you go?

[18:43] can that be considered a bug in the header? [18:43] or is it reasonable to say all userspace using that now has to #include ? [18:43] Kernel question: I'm trying to write an app that talks to USB cameras. Should I use /dev, /proc or sysfs? [18:45] it was added on dec 6 as part of commit "bridge: export multicast database via netlink" [19:55] hallyn, well if in4_addr is defined without additional headers and in6_addr not, that sounds like a bug [19:56] * rtg -> EOD [19:56] apw: i suspect in4_addr is also not defined [19:56] apw: but that isn't used in if_bridge itself [19:56] oh hmmm, i wonder why in6_addr is used [19:57] apw: see https://www.redhat.com/archives/libvir-list/2013-January/msg00957.html. it was used as of a commit on dec 7 [19:58] oh, i see. i thought the thread on netdev had died, but i guess it's more recent than i thought, so still on-going [20:01] hallyn, well that doesn't really resolve ... but hopfully will [20:03] apw: right. hopefully. meanwhile i'll work around it in libvirt (using the upstream patch) but i expect more build breakages in raring === henrix is now known as henrix_ [20:56] quantal kernels in precise are not packaged correctly for multiarch [20:56] linux-headers-`uname -r` needs to be Multi-arch: foreign === adam_g_ is now known as adam_g
