Anyone running MP Alpha systems?

It's quiet on the Alpha list!
Is anyone running any multiprocessor Alpha systems for extended periods of
time? I'm seeing lockups of the DS25 I've been testing, and I can't get in
to the kernel debugger, so I'm about to try a uniprocessor kernel for a
while to see if it helps.
Thoughts, anyone?

both processors online. It seems to run OK with GENERIC.MP but "cpuctl
offline 1" in rc.local, so that could be a first thing to try.

I Have a CS20 running NetBSD 7.0 with the GENERIC.MP kernel, I've not
been doing much with it except compiled kernels and some packages.
It's currently offline since it generates a bit too much heat... Maybe
I should fire it up again an see for how long it will run?

Hi All!
Yes, I'm runnig OpenBSD MP kernel on API CS20 for testing MP
implementation. All working fine. I used NetBSD on the same machine a few
time ago.
Best,
Rafa
