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

drm/nv50/disp: move remaining interrupt handling into core
Signed-off-by: Ben Skeggs <<a href="mailto:bskeggs@redhat.com">bskeggs@redhat.com</a>>
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
at 0x400724
