panic: cleaned vnode isn't

I just got this panic on a recent 2.5.1

System is DragonFly v2.5.1.631.g711a0-DEVELOPMENT from 2010-01-22 running on a
Core 2 Duo system with 2GB RAM

The machine is a NFS server for pkgsrc distfiles.
It was extracting a distfile locally and a NFS client was also extracting a
different distfile when the panic occurred.

The filesystem is a Hammer v4 volume created recently. It is not an upgrade of
a previous hammer version:

Filesystem    Size   Used  Avail Capacity  Mounted on
SAMSUNG.160   144G    22G   122G    16%    /

A brief transcription of the panic message:

panic: cleaned vnode isn't
mp_lock = 00000001; cpuid = 1

Even though I entered "call dumpsys" on the db prompt, there was no crash dump
after the next boot.
