Unfortunately, it will be hard to determine what update prompted this issue as I didn't notice the problem right away. However, recently my Thinkpad x220 began experiencing a 10 C increase (as reported by sensors) and a 1k increase in fan RPM on resume from suspend. I started to suspect the suspend being the culprit, so I ran sensors, it came back with 44C temp on my cores, and a 1900 fan RPM. I suspend the system and then bring it back. If I run sensors again immediately upon resume the core temps have risen to 55C and my fan RPM is around 3K. A reboot of the system corrects this issue and brings the temp and RPM back to the pre-suspend numbers.
System is up to date and uses Kernel 3.6.1 and testing repo. I am getting ready to back down from testing to see if the problem goes away, but, has anyone notices similar behavior?
Update: I have narrowed the problem to kernel 3.6.1. Temp and fan are working normally after moving back to 3.5.6.

This should probably go in the Testing section.
