CurrentDmesg.txt seems truncated? Are there no DRM related messages in dmesg when the problem occurs? The description seems rather vague as to what the problem is exactly, but I'm guessing it might be related to GPU lockups and recovering from them.
Is there something that triggers the screen to blank? Does disabling desktop effects help? There were some display watermark fixes for igp chips in 2.6.35, they might help avoid the screen blanking issue if it's watermark related: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commit;h=07d4190327b02ab3aaad25a2d168f79d92e8f8c2 http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=f892034a8ce80ed7098f667aae2eb6300e570603
