(kgdb) list *0xc0308af9
0xc0308af9 is in g_dev_strategy (/usr/src/sys/geom/geom_dev.c:401).
396             KASSERT(cp->acr || cp->acw,
397                 ("Consumer with zero access count in g_dev_strategy"));

399             bp2 = g_clone_bio(bp);
400             KASSERT(bp2 != NULL, ("XXX: ENOMEM in a bad place"));
401             bp2->bio_offset = (off_t)bp->bio_blkno << DEV_BSHIFT;
402             KASSERT(bp2->bio_offset >= 0,
403                 ("Negative bio_offset (%jd) on bio %p",
404                 (intmax_t)bp2->bio_offset, bp));
