 The same effect (with a slightly different stack, but same panic) can be 
   achieved by copying files *from* the MSDOS filesystem to a FFS 
 filesystem (ie, 'cp /mnt/msdos/netbsd* /', where / is a FFS).
 
 panic: kernel diagnostic assertion "bp->b_vp == NULL || bp->b_vp->v_tag
 != VT_UFS || ISSET(bp->b_flags, B_COWDONE)" failed: file
 "../../../../kern/vfs_bio.c", line 888
