:I'm not able to reproduce this at will at the moment. The PR I mention
:has a program which it claims can cause the crash, which I will try
:running. I'll also try tailing various logfiles, including the one which
:caused this crash, which is being written to on the machine that is the
:NFS server.

In looking at the code the solution may simply be to loop back up
to the top of vinvalbuf() instead of panic if we wind up with
buffer cache buffers. If V_SAVE is set the act of writing dirty
VM pages can cause new buffer to instantiate and result in the panic.
But I would really like to get the bug reproduceable to make sure
that the solution really does fix it.
