I have to revise my earlier observation. I encountered the crash again today. (Even with updated bios 1.52).
I attached a log file including 1. some lines from .xsession-error 2. the output when I try to start "unity" from terminal after the crash but before reboot 3. dmesg at time of crash 4. /debug/dri/0/i915_error_state at time of crash ** Attachment added: "Multiple logs" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1177775/+attachment/3789727/+files/bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1177775 Title: [drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1177775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
