Yes, I just newfs'd a lfs into a ffs - from a similar situation.  Was
getting massive numbers of lfs_markv messages but a quick investigation
didn't show any changes in that specific area.  I wasn't getting any bad
lfs_cleanerd messages - just the normal "finished segment ..." stuff.

Then I ended up having it panic every time on mount - or IIRC just after
when lfs_cleanerd had started (and, yes, my kernel/userland are aligned).
Since I can't keep that specific machine down long enough to investigate
and I didn't expect to be able to reproduce it easily, I hadn't send-pr'd
it yet.
