Thanks for the pointer. That was informative.

However.

I have ran Ubuntu 14.04 Live for days without any issue.

I mean, I can also just say: Yeah, spend another $40 on a DDR2 system...

The guy also doesn't mention what he replaced it with, and the 955 was 
what I wanted to replace mine _with_ rather than get away from ;-).

I can't go randomly test $40 CPUs and the only one I have left I 
think...

Well whatever.

I could check if the hang occurs during such a message but the above 
thing you quoted happened without a hang.

Other than that my symptom appears to be the same as the thread you 
linked.

I'm just a bit annoyed at the thought of throwing random hardware at 
what is basically a kernel problem... :(.

I have not had a hang thus far though after the CMOS reset.

Of course I am grateful for the hints and pointers and feedback.
