This was the first thing I tried. The kernel survived for a bit longer
- something like 3-4 days instead of usual nightly panic attack, but
finally it crashed in the same place with nmp=0xc. This suggests
that vnode's vp->v_mount has already been reused for something else.

This carsh confuses me a little - if filesystem is unmounted,
shouldn't all vnodes associated with it be gone? If so, then how comes
this particular rogue vnode was still around?
