As mentioned in IRC, according to your logs your 3.10.9 suspend issues are not
caused by nouveau

Whereas for the 3.11 one it seems that we've introduced a regression

I would recommend a git bisect between 3.10 and 3.11 as there are quite a few
commits related to your card. I would check dmesg on each step to establish
which commit introduced the following messages (and most likely the whole s2r
issue)

nouveau  [     DRM] MM: using COPY0 for buffer copies

There are others having trouble with NVC1 on 3.11+, see bug 69203.

Seems like there was one more step to complete the bisection.

Either way your issue/dmesg looks exactly the same as bug 69203, despite that
you've notice it at a later stage (when you s2ram).

*** This bug has been marked as a duplicate of bug 69203 ***
