If that can serve: I got _exactly_ the same problem on one machine that
was otherwise stable for months. It turned out that updating adpatec
BIOS (1.23 and 1.32 to 1.34.2) and disabling auto-termination solved the
problem. Unfortunetly, i can't say what of the two actions fixed this
for me since i made the two at the same time.
