So, finally got round to creating updated logs (including DebugFlushCaches). Updated upstream information, duplicating here just in case. -----
Slightly updated test case (hopefully not too many changed unknowns, had to do an system update): -mainline kernel 2.6.32-020632rc6-generic, rc5 is still on the machine if wanted -current X.org drivers from 'xorg edgers' PPA: 2:2.9.0+git20091106.dbb68168-0ubuntu0tormod I have also enabled the Option DebugFlushCaches in xorg.conf. Updated batchbuffer dumps and logs are attached. I do not know if this is relevant, but the X freeze produces lots of repeated lines in dmesg like this: --------------------snip!-------------------- [ 180.008194] [drm] DAC-6: set mode 640x480 0 [ 180.498662] [drm] DAC-6: set mode 640x480 0 [ 288.356030] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
