** Description changed:
On some Intel GM965 machines, running OpenGL applications (eg. Blender,
Second Life, the Endgame screensaver, Scorched3D) can crash the system.
Symptoms: Colours go funny, then screen flashes between off and black with
'please wait' cursor about 10 times, then stops; does not respond to
Ctrl+Alt+F1 or Ctrl+Alt+Backspace, but does reboot on Alt+SysRq+b. Logs the
line
Error in I830WaitLpRing(), timeout for 2 seconds
in /var/log/Xorg.0.log.old
(Please note that this is not the only X crash bug; if you cannot find
an exact match for your symptoms then please file a new bug.)
Workaround: Adding
Option "DRI" "false"
to the graphics controller Device section of /etc/X11/xorg.conf avoids this
bug, but may drastically reduce performance.
This bug has been reported upstream and you can follow the link to xorg
bugzilla, but as of 29.12.07 no developer managed to reproduce this bug (how to
trigger it seems to be hardware dependent, with some i965s not appearing to
have it at all) so it will be very hard to fix unless that changes
if you are suffering from this bug please go to xorg bugzilla and report your
hardware specifics.
also please edit this bug description and add the name and exact model of
your affected laptop.
