Yes, absolute storms of them! I had to comment out the error reporting
code in fs/nfs/dir.c because the overhead of flushing the messages to the
system logs was bogging down the system. Like Olaf, I assumed they were
normal - and remained from your original alpha testing.

I'm also seeing a flood of "inode mismatch" messages, but not in the same
order of magnitude as the "fh changed" ones <g>.

Seriously, if this is not a good thing, let me know what I can do to
help you home in on it!
