seen after today's apt-get upgrade on a previously-working 13.10 installation on HP xw8400 Workstation. I hadn't logged in for weeks, so not sure if the transition from xserver-xorg-video-nouveau 1:1.0.8-0ubuntu3 to 1:1.0.9-2ubuntu1 was the critical event.
Notable dmesg events are attached. including [ 684.095667] ------------[ cut here ]------------ [ 684.095729] WARNING: CPU: 0 PID: 1949 at /build/buildd/linux-3.11.0/drivers/gpu/drm/nouveau/nouveau_bo.c:151 nou veau_bo_del_ttm+0x77/0x80 [nouveau]() [ 684.095822] CPU: 0 PID: 1949 Comm: Xorg Tainted: GF I 3.11.0-3-generic #8-Ubuntu [ 684.095824] Hardware name: Hewlett-Packard HP xw8400 Workstation/0A08h, BIOS 786D5 v02.26 09/21/2007 [ 684.095826] 0000000000000009 ffff880114fadc00 ffffffff816f0d91 0000000000000000 [ 684.095830] ffff880114fadc38 ffffffff81061ced ffff880113509c00 ffff880114aed800 [ 684.095833] ffff880114423170 ffff880113509c00 ffffffffa0236540 ffff880114fadc48 [ 684.095837] Call Trace: [ 684.095845] [<ffffffff816f0d91>] dump_stack+0x45/0x56 [ 684.095850] [<ffffffff81061ced>] warn_slowpath_common+0x7d/0xa0 [ 684.095855] [<ffffffff81061dca>] warn_slowpath_null+0x1a/0x20 [ 684.095881] [<ffffffffa01ce7b7>] nouveau_bo_del_ttm+0x77/0x80 [nouveau] [ 684.095893] [<ffffffffa00fc6e9>] ttm_bo_release_list+0x89/0xc0 [ttm] [ 684.095902] [<ffffffffa00fd95c>] ttm_bo_release+0x1bc/0x2e0 [ttm] [ 684.095911] [<ffffffffa00fdaa9>] ttm_bo_unref+0x29/0x30 [ttm] [ 684.095937] [<ffffffffa01d204b>] nouveau_gem_object_del+0x4b/0x70 [nouveau] [ 684.095957] [<ffffffffa000594a>] drm_gem_object_free+0x2a/0x30 [drm] [ 684.095971] [<ffffffffa0005eee>] drm_gem_object_release_handle+0xae/0xd0 [drm] [ 684.095977] [<ffffffff8135a304>] idr_for_each+0xa4/0xf0 [ 684.095991] [<ffffffffa0005e40>] ? drm_gem_handle_delete+0x170/0x170 [drm] [ 684.095995] [<ffffffff816f4312>] ? mutex_lock+0x12/0x2f [ 684.096009] [<ffffffffa00066e0>] drm_gem_release+0x20/0x30 [drm] [ 684.096045] [<ffffffffa0004d11>] drm_release+0x5a1/0x620 [drm] [ 684.096058] [<ffffffff811a7981>] __fput+0xe1/0x230 [ 684.096069] [<ffffffff811a7b1e>] ____fput+0xe/0x10 [ 684.096080] [<ffffffff81081384>] task_work_run+0xc4/0xe0 [ 684.096085] [<ffffffff81064157>] do_exit+0x2b7/0xa40 [ 684.096089] [<ffffffff81097f59>] ? vtime_account_user+0x69/0x80 [ 684.096093] [<ffffffff8106495f>] do_group_exit+0x3f/0xa0 [ 684.096096] [<ffffffff810649d4>] SyS_exit_group+0x14/0x20 [ 684.096101] [<ffffffff81700e2f>] tracesys+0xe1/0xe6 [ 684.096104] ---[ end trace c5f683f3e85eee1a ]--- ** Attachment added: "crash log from HP-xw8400" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1208207/+attachment/3797369/+files/nouvea-crash -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1208207 Title: driver crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1208207/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
