'k, I'm working on getting a serial console working on one of the 3 
servers that I'm getting these 'deadlocks' on ... I've upgraded the OS to 
the latest -STABLE (so that I'm not wasting ppls time on a bug that might 
already be fixed), and adding in the various options as detailed in the 
handbook URL above ...

First question, what should I expect?  A bunch of messages to the console? 
A slow as a dog server (ie. the INVARIANTS stuff)?  or nothing until the 
deadlock actually occurs?

thx ...
