I should have added:
CC: stable@xxxxxxxxxx
This patch is really trivial and safe and should go there.

Be aware that it's not related to suspend, but to all multi core machines that
make use of the "managed core" cpufreq implementation (this is when
/sys/devices/system/cpu/cpu1/cpufreq is a link to ../cpu0/cpufreq) and when a a
_PPC cpufreq BIOS limitation event is thrown to a managed cpu core (in your
case the latter always seem to happen on suspend).

Dave, can you pick these up, please.
This would be:

The patch from comment #6:
http://bugzilla.kernel.org/attachment.cgi?id=23870
for your next branch and

The patch from comment #10:
http://bugzilla.kernel.org/show_bug.cgi?id=14391#c10
as a riskless regression fix which should go to mainline/stable kernels asap.

Ehh, I cannot change the status, should be code available.
