I just recreated the volume, so I didn't have a chance to try that.

Not sure, at least a couple months old, and the kernel was last updated
yesterday. lfs_cleanerd updated yesterday as well, and it still paniced
doing some things. After I remade the lfs filesystem, everything seems fine.
I've also stopped seeing the lfs_markv messages.

I just used newfs_lfs /dev/rwd1a, without any special block/frag size
options, so I'll see how it goes. So far so good.
