 I have updated head a bit to handle some edge cases better.  I'll send a
 patch into this ticket for 9.1p4 for you to test.
 
 In the meantime, can you update your kernel configs with
 BREAK_TO_DEBUGGER or ALT_BREAK_TO_DEBUGGER so you can get a dump when
 the system stalls?  We might be able to determine what the system is
 waiting on and give us a clue to what the issue is.
 
 If you are able to get a system to stall with this set, break to the db>
 prompt on the serial console, and email the output of "alltrace" here so
 I can do some analysis. =20
