  I'm not sure if I still have a network boot active, but it shouldn't 
take too much to enable it (I had clobbered my boot disk at one point and 
couldn't get another disk to boot and had to setup network booting to fix 
the disk).

  Serial interrupts need to be working, so they are probably blocked at 
that point.  Halting with break should show you the PC and PSL, which can 
be used to determine where it's hanging.  You can then enter continue and 
repeat, and see if you get different values for PC and PSL.
