Weird keyboard lockup

[Tarjei Knapstad]

A colleague is experiencing some weird keyboard lockups under FC4
(fully updated). After some random interval of about 1-2 hours it
looks like X just stops receiving keyboard events, not even responding
to Ctrl-Alt-Backspace. The mouse works just fine, and I can start a
terminal and enter commands by pasting bits and pieces using the
mouse. The box has an ATI graphics card (Radeon 9600), but uses the
stock X 'radeon' driver.

The end of /var/log/Xorg.log.0 looks like (repeated several times):

SetClientVersion: 0 8
   SetGrabKeysState - disabled
   SetGrabKeysState - enabled

Any ideas to what could be wrong/how to fix this?

Thanks,

Upon closer inspection the box wasn't entirely up to date (running an
old kernel++). Will try a complete update and see if that magically
solves the problem :)

I've had similar problems on an FC5 system with a Radeon card.  The
problem seems to be provoked by playing audio: the first symptom is loss
of the panel.  If I get to it fairly quickly, I can cure things by
killing artsd; then the panel reappears, and the system recovers.  If I
don't kill artsd fairly fast (no time estimates available), I lose the
keyboard and sometimes the mouse.  Note that the system is x86-64.

System info:
        Processor: AMD Athlon(tm) 64 Processor 3000+
        System: FC5 with all updates
