Server aborting. in process of doing some stress testing on the driver due to hang i was experiencing, was doing a lot of "coverflow" type application switching in compiz and crashed with this backtrace in X. including Xorg log file.
btw, I can easily reproduce this. i just initiate compiz's shift switcher and and quickly cycle through windows (i.e. hold down arrow key). results in this crash quickly.
I got the same problem ob my Radeon 9700, using Compiz and EXA acceleration. It first happened when I was browsing lots of Photos in Nautilus Thumbnail view, but today I found a really fast way to reproduce it: 1. Get MPEG4 Modifier from http://moitah.net/ and run it with mono. 2. Drag the lower right corner of the file-open dialog arround to resize it (which causes a lot of redrawing). 3. After some seconds X will crash.

I'm also experiencing this bug. It seems that the crashes are very random.
