No, there's no other open bug report for this. It's better to keep this one
open as long as it's not fixed upstream.

I had the exact same crash today.
After disabling my vga card, and shutdown I got the following trace:

Can you confirm that this issue still exists in the latest kernel (3.11-rc7)? A
bunch of locking/ordering stuff has been redone since 3.8, I think.

I just tested with 3.11 and I can can confirm that suspend/resume works,
however still crashes on shut down/reboot.

Can you supply a full kernel log that includes the backtrace from 3.11? You can
probably trigger the issue by unloading the nouveau module -- see how to do
this at http://nouveau.freedesktop.org/wiki/KernelModeSetting/ (you can't just
rmmod it, you have to unbind the console first)

Ok, I had some time to try 3.12... it's even worse, kernel crashesh short time
after loading nouveau module. Starting X completely locks the system.

Is this still an issue in 3.13.x or later? The runpm stuff should be there and
working, with the card automatically powering off when not in use.
