[K12OSN] Kernel panic on client boot

[David Hopkins]

Sometimes, after a server has been up for weeks, clients will start
getting the kernel panic error on (re)boot. It seems to somehow be
related to NFS services (or tftp, not sure which) going down. I have
tried restarting nfs and other services, but that never fixes the
problem. Simply rebooting the server does correct the issue, but would
appear to be overkill. Any client systems that are already up,
continue working, but no new clients can connect.  Has anyone seen
this, and even better, found a way short of a system reboot to fix it?
