I've had similar problems with a OC-3137 (PCI/II 16/4) card in a Digital
Venturis P75 machine, but I managed to break the machine completely before
looking into it any further.

The symptoms were very similar to yours. The machine would be fine as long
as I didn't use it much, but doing anything which transferred data at a high
rate would cause the card to fall over. Even doing an `ls -al` on a large
directory would cause the link to fail, however downloading a 100MB file
over our 512K WAN link was fine, therefore it's almost definately speed of
delivery and not quantity of data which is the problem.

IIRC though, I couldn't `ifconfig down` and then `ifconfig up` the interface
to restart it, a powerdown was the only option.
