I've run into the SMP lock / hang issue with FC1. Is this issue resolved in FC3? The machine in question is a production box, so I don't really want to risk a repeat of the previous hang behavior. I've been running in uniproc mode for a long while and have had good reliability, but having that second processor in use would be very nice. A scan through the list archives didn't turn up any discussion on this issue after late last year...
Thanks.

"The" SMP lock / hang issue?
It's not clear to me exactly what you're talking about: can you give some more detail?

Lockups / hangs that occur only in SMP mode generally mean there's a bug in part of the kernel. There's been a lot of work done on SMP mode and using SMP mode, so there's a fair chance the issue you were seeing has been addressed. But without more details it's hard to say.
FWIW I've run every RHL then every Fedora since late 1999 on SMP hardware, and have never seen a problem (except once on a 2.5-era development kernel...)
