** Attachment added: "dmesg when the above segfault happened" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/780809/+attachment/2124478/+files/dmesg.20110511
** Description changed: 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 hanging is related to bug #727594 since my chipset is - newer than those that are known to cause lockups. + on a separate occasion. gdm log for this case is also attached.
