dmesg for boot and one suspen/resume cycle

Since 3.7-rc7 from the nouveau git, the screen of my laptop will not turn on
after resuming from suspend to RAM.

I have bisected the problem to the commit

bb49f2c0dbff280c20830a1b303844fc604a611c is the first bad commit
commit bb49f2c0dbff280c20830a1b303844fc604a611c
Author: Ben Skeggs <bskeggs at redhat.com>

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

    Signed-off-by: Ben Skeggs <bskeggs at redhat.com>

In the current nouveau kernel git the problem still occurs, the bad commit is
14464b8cd643467cb97335eb75ea676260dd0ad8 and applies after 3.7.0.

Dmesg attached, the relevant error is probably:

[   66.285584] nouveau E[    PBUS][0000:01:00.0] MMIO write of 0x00000000 FAULT

dmesg for boot and one suspend/resume cycle with 3.8.0-rc2 form today's git
master

Suspicious error messages are now gone, display still does not turn on after
resume on my machine.

What information would be helpful for further debugging?

correct dmesg for boot and one suspend/resume cycle with 3.8.0-rc2 form
today's
git master

Attached incorrectly collected dmesg. Correct dmesg appended.

dmesg for boot and one suspend/resume cycle with 3.8.0-rc2 form today's git
master with mask patch from bug 59057

Patch from comment 15, bug 59057 does not make a difference.

Looking more closely, I probably have the same machine as Pontus Fuchs.
