[Problem]
X gets stuck in a loop, reporting the following error to dmesg:

 [drm:radeon_cp_idle] *ERROR* radeon_cp_idle called without lock held, held 0 owner ed9589c0 ee2e0880

[lspci]

	Subsystem: 148c:2063

[Original Report]
When attempting to run a 3d game such as Enemy Territory or a game via wine X crashes and locks up. I am still able to ssh into the system but unable to kill X in any way. Exactly the same thing happens using the kernel from Hardy so I'm inclined to believe this not a kernel issue.

dmesg is entirely filled with:

Comment 2 Dave Airlie 2008-12-18 01:12:00 UTC 
is the user running compiz or kwin effects?
Comment 3 Bryce Harrington 2008-12-18 09:34:43 UTC 
Yes, the user only sees the issue manifest while desktop effects (kde 4.1.3) is on.

Then it could be the same problem as bug 7128 / https://bugzilla.redhat.com/show_bug.cgi?id=445331 and friends, due to the AIGLX code dereferncing a stale DrawablePtr.

However, I thought there was a workaround for this in KDE 4.1.3... but maybe that only applies when disabling kwin compositing, and the problem can still be triggered in other circumstances such as the ones described here.
Comment 5 Radosław Warowny 2009-03-03 12:30:05 UTC 
The same issue affects also system without deskop effects activated. The system is Ubuntu 8.10, AMD64, Gnome desktop, RV350.
Comment 6 Radosław Warowny 2009-03-04 14:37:42 UTC 
After changing AccelMethod option from default (XAA) to EXA the symptoms changes to X server restart instead of system hang with the following messages appearing in X log file:
