Almost certainly not. The problem here is more than likely with the
ethernet *driver* and not the hardware. It looks like an 'off-by-one'
error in the driver code which is then being trapped elsewhere in the
driver. Of course, if it *is* a fault in the ethernet controller itself,
it might be causing a similar fault...
I used to work on a large web cache project where we had NICS running at
80Mbps+ in both directions 24 hours a day, and the stability of ethernet
drivers was (obviously) a major concern.

I'd check with Cobalt to see if they have ever updated the Ethernet
driver for the Qube2 first, and then try rolling my own from the source
code. Depends on what you're comfortable with I guess :)
