robert@ is working on an R10K machine as well (an Octane?).  I'm
working on IP22s.

Nothing really works now.  A ton of kernel code is still needed,
currently I'm trying to get exceptions working properly (the NetBSD
code leaves a bit to be desired and doesn't work right @64-bits).
Also I am seeing a lot of unexpected access (deterministic) to bogus
bits of memory, possibly as a result of stack corruption, or a
stack size issue, I'm not sure.  Using random printfs seems to make
these things better/worse non-deterministically, but a printf in a
given location deterministically changes how things work.  This may
be evidence of a compiler bug, but I'm not sure.  Certainly there
are bugs in the compiler.  With -O the compiler ICEs, I seem to
recall.  imp@ suggests maybe it's a cache issue, but I've tried
with L1 cache disabled, with the kernel running in KSEG1, and so
on, to no avail.

Thanx,
juli.
