Well, I know the symptom with "locking up after server restart after crash".
But no Solaris client involved - only Linux clients on Linux NFS server.

I still wait for the next crash to happen (19 days uptime now).
Normally it was crashing after ~14 days.


I use now 2.4.9-xfs but will switch to 2.4.14-xfs if the crash occurs.
I can't trigger the bug though (mounting our "compile environment" on
2 clients, compile some projects and pressing reset on the server)


Instead of shutting down the clients, I pull the network cable, start
in runlevel 1, wait, wait a bit longer, !"§$%&, plug in the cable and
hey: it doesn't crash!
