ATAng hang

[Petri Helenius]

My first try with ATAng on -CURRENT as of 18 hours ago ended up dying
around reboot. Other than this, it seems to work as expected.
I don't have WITNESS or INVARIANTS on this box, but I can recompile
kernel with them if  it helps.
# reboot
Aug 28 09:24:35 rms21 reboot: rebooted by root
 boot() called on cpu#0
Waiting (max 60 seconds) for system process `vnlru' to stop...stopped

*** HANGS HERE***, I go over and powercycle...
