I would usually say that mesa was the most likely suspect from the list from 2010-05-06, but looking at the changelog (https://launchpad.net/ubuntu/+source/mesa/7.7.1-1ubuntu3) it is clear that that upgrade does not change anything on intel hardware.
I am a bit surprised about the behaviour describe. Usually, these messages in dmesg output [ 8240.845026] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 8240.845038] render error detected, EIR: 0x00000000 [ 8240.845186] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 730176 at 730170) is associated with the display freezing and only a restart would recover that. I'm not sure if Apport will trigger on this kind of error (partly because I'm not sure exactly what happens). Using the 2.6.34 kernel and see if an error state is captured in /sys/kernel/debug/dri/0/error_state (and attach it here if it is) may shed some light on this (see https://wiki.ubuntu.com/X/Troubleshooting/Freeze#How%20to%20Get%20a%20Batchbuffer%20Dump%20%28-intel%20only%29). You may enable automatic bug reporting for GPU errors by uncommenting the last line in /lib/udev/rules.d/40-xserver-xorg-video-intel.rules, but note that this change will be overwritten on package upgrade of xserver-xorg-video-intel. -- [i945gm] X crashes randomly (lucid) https://bugs.launchpad.net/bugs/587708 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
