 Line 979 of vfs_subr.c in 7.2 is this in delmntque()
 
 979:        TAILQ_REMOVE(&mp->mnt_nvnodelist, vp, v_nmntvnodes);
 
 It looks like this is either a fuse or sshfs bug where it doesn't insert a 
 vnode it created into the mount's vnode list and when the vnode gets
 recycled so it can be used by another filesystem (in this case FFS), it causes 
 a panic.
