Apologies for this late reply, but since I first started experiencing these
problems, and with no end in sight, I just got a bit fed up with it and was
forced to downgrade my kernel - I am sticking with 3.3.x as it seems very
stable as far as the nouveau suspend/resume problems go: I am getting an
occasional "blip" (resume failure) about once every 15-20 suspend/resume
cycles, which to me is as good and as manageable as it could be expected, given
what I experienced with kernels 3.4, 3.5 and 3.6.

I am currently waiting for 3.7 to become mainstream for my distro (I am using
Fedora) so that I could give it a go, but I don't hold my breath to be honest.

Just FYI: the problems I have experienced with kernels 3.4 - 3.6 have been the
same as explained by a few others on here - every second suspend/resume cycle
is a complete and utter failure, without exception. It's like a clockwork.

I haven't applied the patch in Comment#37, but will do as soon as 3.7 becomes
"mainstream" in my distro and will post the results on here.
