Hi,

I cannot start KDE with the 2.6.37-rc3 kernel. The X server and display
manager start normally, but when I attempt to log into KDE, it attempts to
start, but then the X apparently crashes and this appears in the dmesg output:

This doesn't happen with 2.6.37-rc2.

Reverting the following commit:

commit 16790569eddf4d406a16a65f4750f405fa669c52
Author: Alex Deucher <alexdeucher@xxxxxxxxx>
Date: Sun Nov 14 20:24:35 2010 -0500

drm/radeon/kms: fix and unify tiled buffer alignment checking for r6xx/7xx

fixes the issue for me (so everyone involved is already in the Cc list ;-)).


Are you sure you've got the right commit?

Well, as I said, I reverted that particular commit and things started to work.

That shouldn't change the calculation that's failing at all. I'd guess it's
probably one of these:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d33ef52d9db8a36900dd53f2e32db9a521ace259
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f30df2fad0c901e74ac9a52a488a54c69a373a41

I don't know. Perhaps there are some interactions between the two and the
reverted one. I can try reverting these tomorrow if you want me to.

Can you try just reverting this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d33ef52d9db8a36900dd53f2e32db9a521ace259

That helps too.

I think the real issue is a bug in the 3D driver (probably a flush at
the wrong time) that one of these commits exposing.

Well, that's possible, but unfortunately this is a regression in the kernel still.

Thanks,
Rafael
