It's a long shot, but at face value, you might be seeing something like
what I've just had with a new PE 2970, which was an interrupt storm from
one of USB interfaces.  If you can boot on a serial console, add -c to
the NetBSD section of your boot loader and "disable ohci", see if that
helps.

In my case the remote machine has a DRAC card, so everything is serial
based anyway.

See http://mail-index.netbsd.org/port-xen/2009/02/03/msg004728.html for
the more complete resolution.

Might give you a starting point.

Mike.
