I think I better post my Archlinux information here as well:

I run kernel + X + ATI git packages which are now a few days old (since I am
unable to compile mesa-full) but for more than a week, my machine has crashed
at least once or twice a day, sometimes more. I can not ssh to it. I run KDE SC
4.4 with compositing and crashes has a tendency to happen at these occasions:

i) Leaving the machine unattended for a while, so that both the laptop and the
external monitor are suspended or powered off. When I return I have found it
dead a number of times, it just does not wake up.

This has not happened after I turned off "Let PowerDevil manage screen
powersaving", but that was only yesterday so I am not sure if that really made
any difference.

ii) Using "Present Windows" as an effect for window switching with Kwin and
pressing Alt+Tab two or more times VERY quickly has crashed the computer at at
least four occasions.

iii) Pressing (maybe even just hovering, I am not sure) a tab in a KDE app like
Dolphin or GTK app like Firefox has brought the machine down as well.

My laptop is a Thinkpad W500 with a FireGL 5700/ATI Radeon Mobility 3650. Of
the various triggers reported above, the "Present Windows" one has been the
most reliable one for me. I never managed to catch anything in logs though.

I should add though that after turning Compositing off and rebooting, I have
not had any crash so far in about 20 hours with the same usage pattern as
before.
