[Bug 585765] Re: Ubuntu 10.04 random freezes

I have the same problem on an IBM Thinkpad T41p (Pentium M, ATI FireGL
T2 (RV350) graphics card), so this should not be an x64, hypertreading
or multi-core issue.  I am using the free radeon driver, no proprietary
drivers.

Symptoms: The screen goes black; mouse pointer remains visible, but not
movable; caps-lock light is blinking.  When SysRq is on, the machine can
be rebooted with Alt+SysRq+b, but other SysRq commands or other keys
commands seem to have no effect.  After rebooting, the system logs do
not contain any unusual entries.  The problem occurs randomly and seems
not to be correlated to memory load, disk activity or network traffic
(internal WLAN is on though).

The same problem occurs with Ubuntu 10.04 and Fedora 13, but never with
Ubuntu 9.10 or Fedora 12.  Therefore, we should probably concentrate on
those components that changed from Ubuntu 9.10 to 10.04 *and* from
Fedora 12 to 13.
