Sorry to be making noise here again, but I was eager to verify that the fixes in v3.13-rc3 were OK on my system. Unfortunately it seems this patch completely broke suspend for me. Hibernete ended up with a blank console and no visible activity, without ever writing any image to disk.
There really weren't that many suspects between v3.13-rc2 and v3.13-rc3, so I went directly to reverting 5a87182aa21d ("cpufreq: suspend governors on system suspend/hibernate") which fixed the problem. I didn't bother debugging it further from there. I don't think there is anything magic about my system which should make this problem specific to it.
I am still using the acpi-cpufreq driver on an old x86_64 laptop if that matters.
On an x86 (32 bits) laptop hibernate also broke in v3.13-rc3. On that machine hibernation itself worked, or at least seemed to work, but the machine would basically stop after thawing (directly after loading the hibernation image).
And reverting commit 5a87182aa21d ("cpufreq: suspend governors on system suspend/hibernate"), on top of v3.13-rc3, also lead to a successful hibernation/thaw cycle.
OK, reverted.
I'll send a pull request with that revert shortly.
Thanks, Rafael
