This appears to be 100% reproducible with this Xorg on Ubuntu's 2.6.27-7. I don't actually care about that configuration, though (I just happened to be booted to that kernel due to triaging another bug, and noticed that X didn't work) so maybe it's not worth pursuing. xorg 1:7.4~5ubuntu18 xserver-xorg 1:7.4~5ubuntu18 xserver-xorg-core 2:1.6.0-0ubuntu14 xserver-xorg-video-intel 2:2.7.1-0ubuntu1~xup~1 xserver-xorg-video-intel-dbg 2:2.7.1-0ubuntu1~xup~1
It is not recommended to use pre-2.6.28 kernel with 2.7 driver. Can you try a newer kernel? 2.6.30 will be the best.
(In reply to comment #2) > It is not recommended to use pre-2.6.28 kernel with 2.7 driver. Can you try a > newer kernel? 2.6.30 will be the best. Oh, the driver works pretty well with 2.6.29.1 and 2.6.28.10. I didn't realize that it'd been made incompatible, sorry for the noise.
