Ubuntu desktop occasionally got frozen.

Mon Mar 26 12:12:56 UTC 2012

Hi Chris Wilson,

At first I thought it is a bug, so I posted the log messages and hoping to
make some contribution to Ubuntu.
Perhaps there are some compatible problems  between my GPU
and xserver-xorg-video-intel.
I'll try to find solutions through Ubuntu forums first.

Thank you all the same.
