NFS intr

I've been using the NFS intr option:

If an NFS file operation has a major timeout and it is hard mounted, then allow signals to interupt the file operation and cause it to return EINTR to the calling program. The default is to not allow file operations to be interrupted.

The Linux Network Administrators Guide or wlug has more information.

But like others I've had problems when the network share went away. Normally RedHat's fix has worked for me in the past but I recently had it not work. I ended up doing a lazy umount (-l option) to get off of it without hurting the server.
