Same here on my Lenovo X201s (5413FFG, Intel(R) Core(TM) i7 CPU L 640 @ 2.13GHz). It started within three to four of days ago. I received several updates (including new kernel images). So it is hard to trace back. Switching back to an older kernel does not help. My feeling is, that it started when I received some ACPI related packages.

A bug similar to my symptoms is filed at RedHat: https:/ /bugzilla. redhat. com/show_ bug.cgi? id=675433
This problem is very serious. I'm not able to use the system for work.
