"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...)
