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. -- Adrian Cox -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
