When I resume from hibernate, I get the following error after which the whole
system either grinds to a halt or I am forced to log in and then the system
crashes:

Here is some information on my card you may find useful:

The above error happens every 2nd time I resume from hibernate - without fail,
like a clockwork. The first time the resume is OK - no problems. The second
time resume always fails with the above error.

The nouveau version is 1.0.0 20120316.
