Do you think the suspend breakage is related to that patch?

Yes. I haven't really worked out what's going on in there, but it looks like it's losing track of what it has allocated and running out of timer MSRs. Possibly because the CPUs are reinitialized on resume: it "thaws the CPUs", which prints the same CPU information as at boot time - caps, bogomips, etc - so I presume it actually redoes those things. I wonder if this makes the performance counter reservation loose track of things?
