OK, well I'll work on isolating that next, I was hoping the segfault issue 
was related.  It's a lot harder getting traces out of a machine that 
insta-reboots so fast that it can't even finish printing the oops message.

I need my testing machine for some unrelated experiments so I might not 
get a chance to work on this further for a day or two.
