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
nouveau E[    PBUS][0000:01:00.0] MMIO write of 0x00000401 FAULT at 0x002010 [
IBUS TIMEOUT ]
nouveau E[    PBUS][0000:01:00.0] MMIO write of 0x01000000 FAULT at 0x03a54c [
IBUS TIMEOUT ]
