Okay, it finally happened. (aside: I was unable to connect to this forum from either computer while they were linked. I guess it was using the wifi to connect and that was too much for the adapters? anyway, whatever.)
First, there did not appear to be anything unusual in TOP. At least not with ram, which is what I was looking at. There was a whole lot of stuff dumped into the journal, though. So, I’m going to post a rather long one here. The end even says something about broken bios, and complained a lot about tsc.
EDIT: To be clear, the beginning is when the crash first starts. It took a few seconds for the keyboard and mouse to lose power, and that is at the end, where the messages stopped.
