Just a quick observation and a question. Hyperthreading exposed a race
condition in an NT driver of mine that had run for a long time on an SMP
system. The timing is different.

Is there anybody out there who has Windows XP and hyperthreading and
_can't_ reproduce the problem? This is making me nervous about a project
I'm planning, as most of the target machines will be P4s with
hyperthreading running XP.
