Panic in nouveau on resume after 5addcf0a

[Martin Nyhus]

After 5addcf0a (nouveau: add runtime PM support (v0.9)) I'm getting 
kernel panics immediately after resuming from suspend. Unfortunately it 
happens so early that I don't get any more info than the blinking 
keyboard lights...

The nouveau tree still panics up to 2fb9d6c, which fails before I can 
test it.

Any ideas?

Martin
