Description ccc1 2009-06-23 01:31:52 UTC
Created attachment 27031 [details]

harware: Lenovo Thinkpad X200
kernel: 2.6.30-ARCH

How to reproduce:
Running xscreensaver-demo and browsing thru the available screensaver triggers the freeze. Clicking on GFlux made my box instantly freeze twice. Another time the preview of Gears made X freeze. When X crashes the mousecursor can still be moved ....

In my logs files i saw the line:
[drm:gm45_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0

Works fine on my GM45 with Mesa master.  Please update and try again.

i installed mesalib 7.5rc4 (via aur from archlinux) and i'm still seeing freezes.
To trigger it i just select GFlux, then select another G* screensaver, then back to GFLux. After repeating these steps a few times X will always freeze.

last lines in my Xorg.log after the crash:
"(WW) intel(0): ESR is 0x00000001
(WW) intel(0): Existing errors found in hardware state."

Recent archlinux update (updated xorg, intel-driver, mesa, ...) fixed to bug.
