Hi!
Video is broken on thinkpad T40p after resume from suspend. (In X
only, text console still works.)
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?
Unfortunately, not as far as I know.
In this case we probably can't help in any way, it's most likely some
special handling required for exactly this configuration that isn't
document anymore anywhere (Well, we are talking about hardware that is
more than a decade old).
Sorry that I don't have any better news,
Christian.
If yes it might be a good idea to bisect to narrow down the problem.
No such luck. I may try something like "3.0" if we are really
desperate (2.6.X kernels probably won't won't boot with recent
userland), but I suspect it just never worked.
