New question about OS hang up.

There were two reasons I suggested rebooting. The first was that when I 
tried the above steps on my cluster elements they froze during the 
rmmod so I ended up having to reboot them anyway.

The second is that it appeared that the network issue for the original 
poster could be causing other problems and a clean reboot would get all 
of them at the same time.

No argument from me. I've happily fiddled with the driver with the 
system up once I got the right one in.

Cheers,
Nick.
