Bug Description

After installing gutsy, system hang very often, sometimes several times per day.
(There was no such problem in feisty.)
The mouse cursor and screen freezes so I can do nothing, only hard reset or Alt-SysRq-S,E,I,U,B.
Ctrl-Alt-F1 does not work.
There is no single message in /var/log/messages for this moment (I can see the time of freeze on the frozen clock applet)
or in any /var/log/* file.

Note 1: According to memtest86+ results, memory is OK. Also temperature sensors
(on frozen screen) show normal temperature, so temporal overheating is also not the issue.

Note 2: Ctrl-Alt-F1 does not work even after Alt-SysRq-r
