It might have been some issue with just copying over modules.  I installed
a full kernel and the crash went away..at least for a bit.  System crashed
while I was driving home, but serial console is at work..so will check it
later to see if it was the same issue.

I'll build w/debug and dis-assemble it if the problem persists.

Thanks,
Ben
