There are some known issues with the MP kernel that cause odd behaviour,
however it only happens rarely and on certain machines. If the system boots
to a login prompt it is usually fine. Are you willing to try a NetBSD
-current kernel to help rule out a few problems? This one should do (note,
that in -current GENERIC includes SMP support by default).
