Nouveau - May 2013 - Hang on resume - PGRAPH TLB flush idle timeout fail

Hi all,

I have what I think is a nouveau-related bug, but don't have all the
information they as for on the support page, so thought I'd ask for help
here first. My computer will hang after resuming from hibernate/suspend,
sometimes showing a normal lock screen and other times just a white screen.

I have some extracts from /var/log/messages, but no kernel logs since I
cannot get anything working for dmesg (i.e. no VT switching works):

Some system info:
kernel: Linux version 3.7.10-gentoo (root at kai-laptop) (gcc version 4.6.3
(Gentoo 4.6.3 p1.11, pie-0.5.2) ) #2 SMP Thu Mar 21 18:47:39 GMT 2013
Xorg: X.Org X Server 1.13.4

Please let me know what I can do to get some further useful information so
I can file a proper bug report.

Thanks,
Kai
