Not to rain on your parade, but Dag-Erling informed me that there
was problems using NFSv3 over the loopback interface that can cause
lockups.
DES: can you elaborate? you think it may cause problems with amd
since it's like an NFS buffer isn't it and would work over the
loopback...

If there are easily reproducable problems with the kernel nfs client
or server, please report them to me and we can almost certainly get
them fixed.Problems related to amd are harder - it's really up to
the author to fix those if it turns out to be a bug in amd rather then
the kernel. So far, though, most of the recent bugs have been on
the kernel side.

I'm not sure where the concern about loopback stuff comes from. Does amd use the loopback interface to communicate with anything?

:Now on to the NFSv2 fhlen patch testing. I haven't run v2 in several
:months, hopefully it still works :-)
My buildworld using the NFSv2 file handle length patch succeeded as

I've included the patch again for reference. (Note: I didn't write
this patch, refer back to the thread for that info).
