Is there some reason you didn't remove ray from your config or fix the 
code as I described in my original posting?

Can you break into the debugger when the system freezes?  Is your 
system built with INVARIANTS and WITNESS?  Are you running with 
PREEMPTION?  What scheduler?  debug.mpsafenet=1?

How are the devices configured?  What is going on when the system 
freezes?  If you can reliably reproduce the problem please provide the 
steps to do it.

Have you tried reducing the devices in the system to isolate the cause?

I don't have a lot of time for freebsd stuff.  Without a stack trace or 
some hint about where the problem is it''s pretty hard for me to help.
