Hi,

you should build a Kernel with debugging options turned on (DDB, KDB,
WITNESS, INVARIANTS, etc. see the handbook). And then enter the debugger
if the freeze occurs, refer again to the handbook about kernel
debugging.

It may also help to turn OFF PREEMPTION, ie. remove that line from your
kernel conf.
