I've sent Dave a separate message with hints for how to get more
information on this problem.

FWIW, I also have a CS20 which I've been running -current (currently
1.6K) on for a while, and I've been running it in MP mode with no
observable major problems (OK, I'll admit that I've managed to wedge
it once to the point of it requiring a power-cycle to recover; I think
the problem involved ktrace, but I did not pursue this further).

Are you trying to use any particular functionality in the NetBSD
kernel?  Raidframe, perhaps?  I'm not using raidframe, and if I recall
correctly, there have been locking issues in the raidframe code which
have not yet been fully resolved(?), and it's not inconceivable that
these problems could cause more severe problems on MP systems.

I'm assuming as a matter of course that you're running -current on the
systems?  There has gone in machine-dependent fixes to the alpha port
related to MP functionality after 1.6 was released.
