Comment 0 for bug 780809

Binary package hint: xorg

Xserver crashes after use of a few days, with a few suspend and resume cycles in between. I use the ubuntu kernel source 2.6.38-8.42 with the patch of tuxonice 3.2 applied. I don't know yet whether or not tuxonice has something to do with the crash. No error is found in /sys/kernel/debug/dri/0/i915_error_state. One of the log files transferred by ubuntu-bug has the backtrace.

I did not have this problem before update to natty.

Maybe related to the above segfault, there was a problem of a hung GPU on a separate occasion. gdm log for this case is also attached. I am not sure if this hang is related to bug #727594 since my chipset is newer than those that are known to cause lockups.
