Nah, forget f12 problems. Looks a lot more like hardware problems with my motherboard. I think my initial test on f10 worked because the file being checksummed was entirely cached in memory. With a reboot between the writing and the checksumming, both f12 and f10 fail every time.
I guess my next step is to try again with the case open and a fan blowing cool air into it :-).
