Kernel log from boot until resume

Running fedora 12 system with
Kernel kernel-PAE-2.6.31.6-145.fc12.i686

Compiled nouveau from git dated on 03.12.2009.

Resuming from suspend results in unusable screen: usually black. I can switch
to console, and run i.e midnight commander, so the screen turns in to blue, but
still no fonts etc.

I think I ran into some issue resuming on nv50 today as well. But in my case
the laptop was completely locked, sysrq did not even have any effect. After
rebooting, I had no traces at all of the resuming.

So I suspect a regression happened between :
2009-12-04 14:00 Ben Skeggs  drm/nv50: very initial DisplayPort support
3ca22d107d7622ce56e2aac356ead815e7f42d69
and
2009-12-01 15:05 Ben Skeggs  drm/nv50: (hopefully) more correct LVDS output
script selection  91f44d691472ce505bec75cc26e3b185b1556cc7

However the bad? news is that the following suspend/resume went fine. If there
is some randomness involved, it will be harder and longer to test.

But maybe my issue is completely unrelated.

In the last week, I did suspend/resume at least once per day, and it always
went fine. It was a one time only problem for me, so ignore my previous
comment.
