Try turning INVARIANTS and INVARIANT_SUPPORT on in your kernel and see if you
can reproduce this. Also, try to get a traceback in ddb if possible as
sometimes ddb gives more reliable stack traces. It looks like your m is
NULL, in which case the KASSERT() on the previous line should fire if
INVARIANTS is on.
