I'm seeing differing behavior, but basically the machine deadlocks after I 
login via SSH.  Sometimes I get a panic, and sometimes it just deadlocks.  
Here's a panic I got:

LWKT_WAIT_IPIQ WARNING! 0 wait 1 (-1)
panic: LWKT_WAIT_IPIQ
mp_lock = 00000001; cpuid = 0

Freezed right after that.  Unable to get a vmcore.  After that, I rebooted and 
it just froze right after I logged in via SSH.  Had to power cycle to get it 
back.  Machine is completely unusable running your iphdr branch.
