This bug has been also reported in the debian bug database:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=346486

If you follow the link there is also a backtrace and some workarounds.

This is debian sarge running 6.9.0.dfsg.1-4.

I just installed the original tarball 6.9. The error is also in the original 
tree.

Are you still experiencing this bug using a more current version of xorg?

No, haven't seen it for some time now.

I'm closing this one, if you start to experience the problem again, please reopen.

I see this bug on git master when running compiz and either starting a new window or resizing a window. Doesn't happen when moving a window around.

lspci says:
00:08.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01)

The last messages are loads of the following, requiring a hard reset.

(EE) RADEON(0): RADEONWaitForIdleCP: CP idle -22
(EE) RADEON(0): Idle timed out, resetting engine...

I added a return statement into RADEONWaitForIdle so the machine doesn't lock up anymore, but the timout message is of course still there.

Reopening bug, I see this timeout error on git master.

You're saying this change keeps things working despite the timeout messages? If so, the timeout is probably just too short and needs to be extended. Ideally, something like radeon_init_timeout()/radeon_timedout() should be used, to make the actual timeout duration independent of how quickly the various loops are processed.

At any rate, this report originally talked about server startup, so you shouldn't have reopened it but created a new report.

yes, seems to work fine. I multipled the timeout by 100, but still ran into
the issue, so I figured I'd file a bug instead.
