Comment 20 for bug 363305

Just a "me too" with a couple of additional observations
(see my log files and "lspci -v" output attached above):

- All of us reporting this bug seem to share the ASRock Incorporation Device 2e20, 2e22 (apparently the ASRock G43Twins-FullHD board). I've searched long and hard for any reports of the same crash on other hardware, but couldn't find any.

- The crash has been absolutely 100% consistent on UXA since driver 2.6 (Ubuntu Jaunty, and I've been applying every driver and kernel update from xorg-edgers since).

- The system worked fine under Intrepid (Ubuntu 8.10, driver 2.4+kernel 2.6.27) or with 2.6 or 2.7 driver with 2.6.27 kernel (no GEM).

- If this helps, on any kernel >=2.6.28 I tried, driver 2.6 or 2.7 using EXA causes a "failed to initialize kernel memory manager" (see the report in https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/380986, with the same hardware), and, again, this is 100% consistent.

All in all, looks like some sort of memory allocation/management issue with this particular chipset.
Will be glad to provide any further information / try any suggestions.
