What happens is typically this: After transeferring some

effectively dead. If I do a sequence /sbin/ifdown eth0
/sbin/ifup eth0 the upload might resume, but stops again
shortly. The phenomenon seems to occur sooner if the path
to the remote system is _fast_ (low ping times).
You can try applying this patch:
http://developer.osdl.org/shemminger/prototypes/sky2-proc-debug.patch
It will add a /proc/net/sky2/ethX file, which lists the status of the TX
and status rings. You should compare the contents of this file during
normal operation to when the interface has hung.
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.
