Comment 7 for bug 667405

I'd like to reference a post made by solnyshok in a related thread on Ubuntu forums, with some information that makes sense, although it is somewhat circumstantial:

"This morning I used laptop outside, it is quite cold there, so machine was getting colder instead of warmer and it kept crashing. Seems that there is a problem, that if processor is not hot enough (or thermal sensors are not warm enough) it would lockup."

My experience is that I have to power cycle after a freeze, so in effect its a "cold" boot, except for the system temperature of course, which has been warming up over a couple of minutes. Usually by the second or third boot it no longer freezes.

I have some time to do some more tests now, so I will. This will include power cycling by removing the battery, in order to make sure I'm clearing as much state as possible.
