This seems to a problem with the GENERIC MP kernel. The tuned kernel
(SUN4M only, bunch of other drivers removed) that I've been using
works (but performance isn't too great).
I don't know what causes the GENERIC kernel failure.
FWIW, GENERIC.MP and a GENERIC.MP from the nathanw_sa branch
both appear to work "ok" on my ss20/712.
