Subject:  cpu temperature after wakeup

hi all,

after a wakeup from suspending to ram, the cpu temperature (reported by
acpi) for the second core is about 15° higher than for the first core
(core2 duo t7400, x86_64).
i am not sure, if it is just an issue of reporting the wrong value or if
the cpu temperature is actually that different.

on a more or less idle machine: cpu0: 44°c, cpu1: 60°c
doing some work:                cpu0: 55°c, cpu1: 70°c

any idea, what could be the reason? usually both temperatures are quite
similar, after a reboot, it seems to be fine again. i am running 2.6.29,
but i think i already saw it on earlier kernels, i didn't look into it
at that time, though ...

thnx, tim
