Thanks, Daniel. I applied the patch.

The output of 'cat /proc/net/sky2/eth0' under normal circumstances
is here:

http://puma.uio.no/sky2/sky2-status-normal.txt

After the interface hangs, 'cat /proc/net/sky2/eth0' causes the
whole computer to hang completely. No kernel oops or other
messages in the console window. Power down is the only
solution.... :-[ No log entries after reboot.
