Resume regression with nouveau 3.8rc1 (bisected)

[Pontus Fuchs]

Hi,

Starting with 3.8rc1 I get a black screen when resuming after suspend. 
The kernel is alive because I can switch to VT1 and reboot with 
ctrl-alt-delete.

I bisected the problem down to this commit:

186ecad21: drm/nv50/disp: move remaining interrupt handling into core

Hardware is 8400M GS (10de:0427) in a Dell XPS M1330.

Cheers,

Pontus Fuchs
