I am also still experiencing the same issue on NVCF (nouveau for-next from
earlier today), but it is _NOT_ limited to resume at least in my case. I can
also confirm that nouveau.config=PCE1=0 seems to workaround/fix the issue.

The corruption does not happen immediately, but after using the system for a
long time (days) and/or after running some graphics-intensive games corruptions
start to slowly appear (old random data in various windows).
