You don't have any PATA devices at all?  SATA is a lot more resilient to
this type of problem.

Windows will generate a bugcheck on an MCA exception just like Linux.
We have really detailed statistics on Windows bugchecks due to OCA, so I
know this is not a widespread issue at least on Windows.

The stack trace will almost always tell you exactly what device timed
