Hi!
Video is broken on thinkpad T40p after resume from suspend. (In X

Maybe this is related?

Hibernation works well here, including X. (Which has small glitch with
mouse cursor being corrupted until it is changed by application).
3.16.0-4-686-pae Debian 3.16.7-cktt11-1 kernel seems to have same
problem, with same scratch(0x15E8)=0xCAFEDEAD message... so this is
not "new" problem...

Looks like CP init doesn't work. Well is there any kernel where that did
worked?
If yes it might be a good idea to bisect to narrow down the problem.

Christian.
