Buffer strategy message?

[Matthew Dillon]

:I see this message on halt/reboot occasionally.  Is it something I need to
:worry about?
:
:Synching disks...
:done
:No strategy for buffer at 0xffffffe056aabf00
:: 0xffffffe0840876a8: type VBAD, sysrefs 1, writecount 0, holdcnt 0,
:Uptime: 12h9m53s
:the operating system has halted
:\

    It's 'probably' ok, but it isn't desireable.  It means one part of
    the system detached while another part of the system was still using
    it.
