Comment 58 for bug 522998

Markus, can you tell what exactly is being displayed after suspending?
I have to say that suspend worked for me a while ago (after having
upgraded my Thinkpad W510's BIOS) but now, I'm experiencing a similiar
(if not the same) issue like you: When I press the power button (turn
it on again) or open up the lid (if it has been closed previously), it
freezes showing some (kernel?) log.

>>Only hard turning off is possible.
Exactly.

I'm running the 2.6.38-8-generic kernel btw. Unfortunately, I can't
say whether it was an update that led to this behavior.
