Description John Levon 2008-01-09 16:26:25 UTC 
I recently upgraded to latest git master ATI:

commit 10e7636c02478b8ffe183bb0c46229ca0d6584e1
Author: Kristian Høgsberg <krh@bitplanet.net>
Date:   Wed Jan 9 12:47:39 2008 -0500

and using DRI in xscreensaver locks the machine (I can
still sysrq-reboot, but that's it).

My base OS is Fedora 8, see attached Xorg.0.log.

Comment 2 John Levon 2008-01-09 16:27:44 UTC 
I forgot to say: I've enabled EXA, because using XAA gives me screen
corruptions problems even with the latest driver, see:

Comment 3 Alex Deucher 2008-01-09 17:13:16 UTC 
Do any of the following options help?

Option "AGPMode" "4"
Option "AGPMode" "8"
Option "BusType" "PCI"
Comment 4 John Levon 2008-01-13 08:33:48 UTC 
I reproduced the hang with AGPMode == 8, but I couldn't with == 4 or with BusType == PCI. The latter slowed down rendering a lot though, it seemed.

A little more info: things work for some time but at some point (especially
if I run glxgears as well), rendering hangs, and I can't interact with anything
in X. The cursor still works though (so I can move the mouse around).

Please attach the output of lspci -vnn so I can add an AGP quirk for your system.

Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
