Crashing in mesa around here: mesa-git-ubuntu/src/mesa/drivers/dri/i915/intel_context.c: /* Release the buffer storage now in case we have to return early * due to failure to allocate new storage. */ if (buffer->attachment == __DRI_BUFFER_HIZ) { intel_miptree_release(&rb->mt->hiz_mt); } else { intel_miptree_release(&rb->mt); }
Guess it's a regression in mesa 8? Probably should go upstream; would be helpful to know steps to reproduce first though. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed => Triaged ** Description changed: i just update + + <czajkowski> bryceh: alt tab through applications fast + <czajkowski> vlc thunderbird, 2 terminals and 2 chromes out + <czajkowski> seems to make it have a hissy fit ProblemType: Crash DistroRelease: Ubuntu 12.04 Package: unity 5.2.0-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-12.21-ux31 3.2.2 Uname: Linux 3.2.0-12-ux31 x86_64 ApportVersion: 1.91-0ubuntu1 Architecture: amd64 CrashCounter: 1 Date: Fri Feb 3 23:10:11 2012 ExecutablePath: /usr/bin/compiz InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Alpha amd64 (20120125) ProcCmdline: compiz SegvAnalysis: - Segfault happened at: 0x7f109783fd49 <intel_miptree_release+9>: mov (%rdi),%rcx - PC (0x7f109783fd49) ok - source "(%rdi)" (0x00000220) not located in a known VMA region (needed readable region)! - destination "%rcx" ok + Segfault happened at: 0x7f109783fd49 <intel_miptree_release+9>: mov (%rdi),%rcx + PC (0x7f109783fd49) ok + source "(%rdi)" (0x00000220) not located in a known VMA region (needed readable region)! + destination "%rcx" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: unity StacktraceTop: - intel_miptree_release () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so - intel_update_renderbuffers () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so - intelSetTexBuffer2 () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so - TfpTexture::bindPixmapToTexture(unsigned long, int, int, int) () from /usr/lib/compiz/libopengl.so - boost::detail::function::function_invoker4<GLTexture::List (*)(unsigned long, int, int, int), GLTexture::List, unsigned long, int, int, int>::invoke(boost::detail::function::function_buffer&, unsigned long, int, int, int) () from /usr/lib/compiz/libopengl.so + intel_miptree_release () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so + intel_update_renderbuffers () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so + intelSetTexBuffer2 () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so + TfpTexture::bindPixmapToTexture(unsigned long, int, int, int) () from /usr/lib/compiz/libopengl.so + boost::detail::function::function_invoker4<GLTexture::List (*)(unsigned long, int, int, int), GLTexture::List, unsigned long, int, int, int>::invoke(boost::detail::function::function_buffer&, unsigned long, int, int, int) () from /usr/lib/compiz/libopengl.so Title: compiz crashed with SIGSEGV in intel_miptree_release() UpgradeStatus: Upgraded to precise on 2012-02-03 (0 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo ** Package changed: xserver-xorg-video-intel (Ubuntu) => mesa (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/926379 Title: compiz crashed with SIGSEGV in intel_miptree_release() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/926379/+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
