Hmm... I have a pair of machines, each with a pair of SM61s and they've
both been rock solid with 3.0 and 3.1. Both have uptimes of ~26 days and
are fairly busy serving DNS, DHCP, ntp, Kerberos, etc. They're both running
a custom kernel, but whilst upgrading them and before building a custom
kernel they ran GENERIC.MP.

I have a pair of SM50s in my parts box and can bring up another SS20 to see
if I can reproduce the problem. Before I got the SM61s, I did have one of
the machines mentioned above running 3.0 stably with an MP kernel and a
pair of SM50s.
