Hi, there.

I think that some wonderful phase change is underway. (NFSv3)

Well.. I am now using knfsd without Version3, i.e., with nothing special,
on Alpha LX164 SuSE-6.3. I have had no trouble with NFS throughout
2.2.15pre20. Suddenly, when I switched to Linux-2.2.16pre[2-4],
the nfsserver does not work.

Here is the log in the /var/log/messages:

==========================================================

===================================================================

Over there, mountd[185] failed. I don't understand why nfsserver
is failing. I compared those two .config files, one for linux-2.2.15pre19
and another one for linux-2.2.16pre4, I can't find anything special.

This failure happens only under Linux/alpha. It became perfectly OK with
the most recent patch (inode/shrink dcache race fix) of Trond under
Linux/i386. Yeah. NFS had been dying after 1 or 2 days of uptime before
Trond's patch on Linux/i386. Strangely, Linux/alpha was OK without
Trond's patch. But now, regardless of Trond's patch, nfsserver
on Linux/Alpha has be unfunctional since 2.2.16pre2.

What is going on?

Thank you.
