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. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
