(kgdb) up 6 #6 0xc10c075d in launch_requests (rq=0xc122b940, reviveok=0x0) at /usr/src/sys/modules/vinum/../../dev/vinum/vinumrequest.c:396 396 rqg->lock = lockrange(rqg->lockbase, rqg->rq->bp, &PLEX[rqg->plexno]); Since the faulting address is zero, the only thing which makes sense to me is that (rqg->rq == NULL). I don't know diddly about vinum, so I have no idea how it might have gotten to be NULL. You want to talk to Greg Lehey (grog@freebsd.org) about that and/or file a PR now that you've got a stack.
