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= =2E 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 tha= t matters. Bj=C3=B8rn
