    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!
