It looks like this is a kernel issue

2.6.32 works perfectly on my system with my current user space

I git bisected back to 4e2ccdb0409146f8cf64a11b6ef82a9c928ced2a which doesn't really make sense but 3ef884b4c04e857c283cc77ca70ad8f638d94b0e seems more likely

So you say 3ef884b4c04e857c283cc77ca70ad8f638d94b0e is more likely.  Your log shows that you tested it and marked it good.  Was it really good?  If so, then graphics would pretty clearly be off the hook.  If it isn't good, then you need to bisect reset, edit the log, then replay it and continue bisecting.

This bug has been fixed - sorry I should have closed the bug as soon as I noticed

However the last week or so I've been experiencing lots of GPU hangs I think this may have something to do with using the latest cairo from git

However I'm seeing graphical corruptions even using the stable version of cairo in 2D and I can't start compositing on KDE

This is all working fine on a radeon setup with the latest git too, I think the problem maybe with in libdrm as the 2D artefacts appear in the latest testing kernel and a 2.6.33 kernel too

The gpu hangs were caused by using the drm backend for i915 & i965

But I'm still getting a lot of artifacts in 2D using an old kernel & new, using stable cairo and new
