I seem to be able to reproduce this on an Acer Aspire S5 (Ivy Bridge
generation CPU).

This machine appears to crash during resume, but I have not been able to
collect any debug output from that so far.

It has to stay suspended for several minutes in order to trigger this
behavior, but it is reproducible enough for me to try to bisect it
(which I'm going to do tomorrow if time permits).

At this point it looks like the breakage was introduced somewhere between
commits 9abf8acea297 and bb2407a7219760, but I need to verify that the
latter really works.

Thanks,
Rafael
