There appears to be a regression, at least on my machine, the GPU started to lock up randomly (some gnome shell actions, namely the hot corner, cause it more likely than general usage) after longer usage and previous suspend to disk/RAM. It seems not to appear if no suspend has been done before.
It appeared first at 2012-10-26, there have been some updates on related packages before: linux-image-generic:amd64 3.2.0.31.34 -> 3.2.0.32.35 xserver-xorg-video-intel:amd64 2:2.17.0-1ubuntu4.1 -> 2:2.17.0-1ubuntu4.2 I am currently trying the workaround mentioned above and here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/975689/comments/25 The first errors in Xorg.0.log [ 21840.621] [mi] EQ overflowing.
