I'll take a look and let you know if I can think of anything.
A couple of things:
- What arch/net interface is the server running?
- I haven't seen any issues w.r.t. i386, so I'm thinking it might be
some sort of 64bit/alignment problem. (dfr@ replaced the RPC transport
code with a new krpc subsystem for FreeBSD8.0 and known issues w.r.t.
alignment were fixed, but there may be more)
If you wanted to, you could try using the experimental server instead
(-e option for mountd and nfsd), just to see if that makes the problem
go away. (It handles mbuf lists/alignment somewhat differently.)
Good luck with it and I'll let you know if I spot anything, rick
