EC reports that Thermal Table has changed

I have two docks for my ThinkPad T520 running Fedora 17 - one at work and one at home. I suspend my laptop on the
way. Sometimes this doesn't seem to go so well. Today when resuming, my USB keyboard and mice no longer
worked. Found this in /var/log/messages:

Any thoughts? Anything else I can report to assist with debugging?
