Title:
Kernel BUG at
/build/buildd/linux-2.6.35/drivers/gpu/drm/i915/i915_gem.c:4224!
Status in Linux:
Fix Released
Status in linux package in Ubuntu:
Invalid
Bug description:
Computer won't turn screen on after blanking and doesn't respond to
keyboard or mouse. After remote login, the dmesg shows "kernel BUG at
/build/buildd/linux-2.6.35/drivers/gpu/drm/i915/i915_gem.c:4224!".
Wakeups from screen blanks get more and more complicated (require
switch to console and back to X) and finally end in this bug. However,
this bug doesn't need X running it works in single user mode as well.
I believe the system was under a relatively heavy load every time.
This bug happens randomly, but happened twice in three days after
switching back from mainline kernel. I was using mainline kernel for
several weeks and nothing bad ever happened.
