I got now crash under 4.0-RELEASE, with syncer and bufdaemon in the same
vrlock state, pax in flswait. I was in single-user mode using pax to
extract usr archive to newly created raid5 volume. I'm using NFS mount
with flags -3i -r16384 -w16384 over 100Mbit full-duplex link, fxp
driver on both sides. Note that I'm using stripe unit size 512k now,
otherwise same.
Here's handcopy of DDB messages:

I hook up serial console to get full traceback next time, but I don't
have any knowledge for further analysis.
