I'm still digging into this. I do have some ideas what may be involved. There
are about three different cases here

1. VIA chipset bug - known, understood, non SMP
2. A few triton boards - probably a hardware issue
3. SMP - looks like a lock bug.

Running the ikd patch is the best help here. I think it will show you a
spinlock deadlock. The trace from that should find the guilty party
