Interesting note on this:
I have my home directory NFS mounted from another -CURRENT box. If I
enable NFS locking and am running a ULE kernel on the client, I am
unable to log into KDE. It accepts my password but hangs before the
splash/loading screen appears. I can switch to a console and login
there without issues, so NFS isn't completely dead. Strangely, using a
4BSD kernel works fine. This is repeatable on my box (at least it
happened the 2 times I tried each kernel so far).
Hmm, it appears that rpc.lockd died on the server end (at some point,
anyway). I have a .core but it doesn't appear like it's finding any
debug symbols. I build everything with -g, so I don't know why it
can't. I'll keep the core around in case anyone cares. Sounds like the
problems may already be known, so if it's not useful please let me know.
