i had an smp 1.5ZC kernel running for months without a single problem.	i `cvs
update -rsommerfeld_i386mp_1`'d in /usr/src/sys/arch/i386 and compiled the
GENERIC.MP kernel with a few modifications (options GATEWAY, etc...).

i believe that currently this branch doesn't compile with -current (please
correct me if i'm wrong here) but bill sommerfeld sent out some patches which
fix this and allow for compliation.  a quick search of the tech-smp@ archives
should get them for you.
