Let me attach another log of segfault and the output of dmesg.  It
happened shortly after I changed the screen configuration between a
single monitor setup and a dual monitor setup back and forth a few times
using the xrandr command in a gnome-terminal.  Again, there was no error
in /sys/kernel/debug/dri/0/i915_error_state.  Before this, the computer
had been resumed from a tuxonice hibernation.

** 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 hang is related to bug #727594 since my chipset is
+ not sure if this hanging is related to bug #727594 since my chipset is
  newer than those that are known to cause lockups.
