** Description changed: Running my own build of the natty 'master-next' kernel branch - (2.6.38-6.33 at SHA1-ID "5754cb"; based on linux 2.6.38-rc7), the + (2.6.38-6.33 at SHA1-ID "57545cb"; based on linux 2.6.38-rc7), the default unity desktop session makes compiz crash immediately upon login (100% reproducible): - compiz[1388]: segfault at 20 ip 00007ff0cee9702a sp 00007fffc50a9580 + compiz[1388]: segfault at 20 ip 00007ff0cee9702a sp 00007fffc50a9580 error 4 in i965_dri.so[7ff0cee6b000+ac000] The crash does NOT occur when running the natty main kernel (2.6.38-5.32), so this appears to be a regression caused by the master- next branch. Note that I the gnome-panel (classic) session works fine. Also, after unity/compiz crashes, I can then switch to a VT and launch gnome-panel and compiz manually... In that state, "unity --replace" does make the same crash occur immediately. (Effectively, only unity seems to provoke this compiz crash, and it always does so). uname: Linux marconi 2.6.38-6-generic #33~kamal~57545cb (my build from master-next) unity: Installed: 3.6.0-0ubuntu2 (from natty/main) compiz: Installed: 1:0.9.4-0ubuntu3 (from natty/main) libgl1-mesa-dri: Installed: 7.10.1~git20110215.cc1636b6-0ubuntu2 (from natty/main) ProblemType: Crash DistroRelease: Ubuntu 11.04 Package: libnux-0.9-0 0.9.30-0ubuntu1 ProcVersionSignature: Ubuntu 2.6.38-6.33~username~57545cb-generic 2.6.38-rc7 Uname: Linux 2.6.38-6-generic x86_64 Architecture: amd64 Date: Thu Mar 3 11:36:56 2011 ExecutablePath: /usr/bin/compiz InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Alpha amd64 (20101214) ProcCmdline: compiz ProcCwd: /home/kamal ProcEnviron: - LANGUAGE=en_US:en - LANG=en_US.UTF-8 - SHELL=/bin/bash + LANGUAGE=en_US:en + LANG=en_US.UTF-8 + SHELL=/bin/bash SegvAnalysis: - Segfault happened at: 0x7ff0cee9702a <intel_miptree_image_copy+42>: cmpb $0x0,0x20(%rsi) - PC (0x7ff0cee9702a) ok - source "$0x0" ok - destination "0x20(%rsi)" (0x00000020) not located in a known VMA region (needed writable region)! + Segfault happened at: 0x7ff0cee9702a <intel_miptree_image_copy+42>: cmpb $0x0,0x20(%rsi) + PC (0x7ff0cee9702a) ok + source "$0x0" ok + destination "0x20(%rsi)" (0x00000020) not located in a known VMA region (needed writable region)!
