Hi Martin, I finally re-ran memtest86 on the machine since it began to have too many different kind of errors (GPF, invalid instruction...). It turned out that one of the memory modules was bad. I guess my brand new list_debug race condition debugger will be useful in the future, but not now. :) I'll remember to let memtest86 run a few hours more on my new machines next time.
