Forwarding this bug from Ubuntu reporter jean-baptiste: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/446674 [Problem] With the mesa 7.6.0 release, a corrupted low memory error appears in dmesg. Both stellarium and googleearth crash. Downgrading back to a git snapshot of mesa from mid-August makes these problems go away.

Created attachment 30204 [details] dmesg.txt This dmesg is with mesa 7.6
Created attachment 30205 [details] dmesg.txt This dmesg is after reverting mesa to the older version (a git snapshot from mid-august). Reporter reports: "So i downgrade to the old mesa, reboot the computer and no more probleme with stellarium or googleearth and also no more memory corruption in dmesg."
Looks like at least two separate Mesa driver issues and possibly more in the kernel, but none in the X driver.
Created attachment 30360 [details] ThreadStacktrace.txt backtrace from a test with no xorg.conf, to eliminate any of those settings as a suspect.
xscreensaver or any OpenGL application corrupt the filesystem on Thinkpad T42 with Radeon Mobility 7500. kernel - 2.6.32 mesa - 7.7 xf86-video-ati - 6.12.4 ati-dri - 7.7 xorg.conf is empty.
Is this still reproducible with, say, Mesa 7.9.1 or Mesa 7.10? A lot has happened since Mesa 7.7.
