0) It seems I'm running into a similar issue but on a X61. On an
uninteresting Gnome 3 session, running roughly 99% idle, the CPU
temperature usually stays below 50 C. But after a few suspend and resume
cycles, still on an equally undemanding, session the CPU temperature
rises a bit above 60 C.

1) The rather course test
    watch "cat /proc/cpuinfo | grep MHz"

suggests that at this moment the second (of two) cores is stuck at 2 GHz
(which I guess is full throttle). Could that be causing this?

2) I'm running a locally built v3.10, by the way.
