Resume regression with nouveau 3.8rc1 (bisected)

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

There's already open bug report for that:
https://bugs.freedesktop.org/show_bug.cgi?id=58729

And my nv92 does not resume too, with similar symptoms, since nouveau display
rework hit the tree.

Hi, I tried that patch but it didn't help :(

I see this in my kernel log after resume:

nouveau E[     PFB][0000:01:00.0] trapped read at 0x002001a020 on 
channel 0x00007b23 SEMAPHORE_BG/PFIFO_READ/00 reason: PAGE_NOT_PRESENT
nouveau E[    1177] failed to idle channel 0xcccc0000
[TTM] Failed to expire sync object before buffer eviction

Sigh, this seems to be another issue :/
Please follow http://nouveau.freedesktop.org/wiki/Bugs and open new bug report.
