> Christian, any ideas?

Not at all, the patch should just change order in which memory is allocated
(from the top instead of the bottom).

The only possible reason that sounds logical is faulty memory, but then it
would be rather unlikely to only happen on suspend/resume.

Another possibility is that some engine can't access certain addresses, but the
dmesg clearly shows that this system has only 256MB of VRAM and that's rather
unlikely under those conditions.

Just speculating, but maybe eviction on suspend doesn't work correctly?

I'm using an RS880 based laptop for typing this message and this box is working
perfectly fine with 3.15.

Have you tried newer kernels as well? E.g. 3.16 or 3.17-rc?
