[1.] NFS client hangs when X is running (2.4.20)
[2.] The NFS client is running Linux 2.4.20 (but I also saw this same
problem on another system running 2.4.18). The NFS server is running
OpenBSD 3.2. Both are i386 systems. I mount /home from the OpenBSD
system onto the Linux system with option "nolock". Everything is
OK until I start X. About 15 to 30 seconds after X starts, the NFS
mount hangs. Any process which attempts to do anything to any file
on the NFS file system goes into catatonia and cannot be killed
(even with -9; ps shows 'D' for state).
This problem does not occur with any 2.2.x kernel. I have tried building
2.4.20 with and without CONFIG_NFS_V3 enabled; same results.

[5.] nfs: server pegasus not responding, still trying
However, this is erroneous. Pegasus (the OpenBSD box) responds
perfectly to ping, showmount -e, ssh and so on. Any existing ssh
connections to pegasus continue working, even ones I started in an
rxvt window in the 15-30 second period when the NFS subsystem hadn't
locked up yet. No other errors are reported.
