I ran:

% stress --cpu 2 --timeout 7200
stress: info: [14967] dispatching hogs: 2 cpu, 0 io, 0 vm, 0 hdd
stress: info: [14967] successful run completed in 7200s

And just to be sure, I also thew in a couple of these:

% dd bs=10 if=/dev/urandom | bzip2 -z -s -9 -c > /dev/null &

and let the latter run for 8 hours.

I saw some new peaks on the 'acpitz-virtual-0' sensors, but the
'coretemp-isa-0000' sensors didn't budge.

Right, that was the theory I was going on based on the FAQ entry I
quoted. Apparently not the case here.


So this would appear to be a problem with the coretemp kernel module.
This CPU (Intel Core 2 Duo P8400) is from the right era to be supported
by coretemp. Where is the best place to go to file a bug against that
module?

Thanks for the suggestions.
