Apparently there is a bug or a setup problem in the kernel they are using.

My wife's machine gets up to 78C occasionally and the problem I see is the 
;storm' of messages put out by the kernel (about 5 per second) eventually send  
syslog and  kern.log into the Gigabyte size range,  filling up the root 
partition.

I've reported the problem but others are seeing it too.   I finally did a sym-
link for both of those files to /dev/null  as a temporary measure.
