xorglog of a crash

The XServer crashes one in while, leaving me with black screen, that has a little area of "colored lines" (some kind of garbage data). The Display is "lost", I cannot change to other pseudo-terminals (ctrl+alt+f1). However the Kernel seems not to be affected, I can restart the computer with ctrl+alt+del or shut it down cleanly by pressing the power button.

I have attached to Xorg.0.logs which both show indications that this might be the intel driver's fault:

Ring at virtual 0xa7914000 head 0x1da6c tail 0x1dc00 count 101
Ring at virtual 0xa7914000 head 0x1da6c tail 0x1dc00 count 101

Ring at virtual 0xa7914000 head 0x1da6c tail 0x1dc00 count 101
Ring end
space: 130660 wanted 131064

FatalError re-entered, aborting
lockup


Note that I am using E17's compositing, so 3D-acceleration is used continuously. Using certain heavy 3D-Apps like games, does not seem to increase the chance for a crash. Actually they have never occured while playing a game. Only during desktop-usage.


Note also that I have other severe problems under FreeBSD [1] whose symptoms are completely different though, so probably unrelated.


unames output on Draco:

OT: it sure would be easier if one could upload multiple attachments at the same time...  ;)
Comment 4 Gordon Jin 2009-01-18 02:23:54 UTC 
This seems similar to bug#17638. Does setting the ExaNoComposite option make it work?
Comment 5 Hannes 2009-01-29 08:21:36 UTC 
Yes that seems to stop the crashes. But of course it implies that I have no compositing.

=> this is duplicate of bug#17638
