Well folks, thank you all so much for your time and energy. Adam, thanks
for your patience. Looks like this is a hardware issue, I don't know why
it didn't crop up before when I was load testing F 15 and Windows, but
after jumping into Windows to try and get the temperatures, as
suggested, for a point of comparison the system over heated and shut
down. In fact it did it twice in a row, so that is more than enough
confirmation for me, I will be talking with Lenovo to get new hardware.

I will also close up the bug report I filed. Thanks again for your
patience and the information, I learned a lot during this process.
