Your commit does make things better, I don't see any stalls on the
first resume.
However, a subsequent s4 causes the stall to re-appear on resume, and
this time there are no stall messages; the kernel just sits there
spinning on something. I've not found the solution to this one yet (I
had a commit similar to Marcelo's in the works, which got me to the
previous works-but-stalls behaviour).
