I just can't move any traffic. no rx's and my tx's only move counters in the driver - they don't actually make it to the wire. if I do "ifconfig eth0 down; sleep 30; ifconfig eth0 up" all is well immediately after the up.. The driver doesn't seem to be doing anything different in either case - its as if the NIC itself is enforcing some kind of quiet period. I'm really writing to see if I'm crazy and hoping someone else can corroborate this is what they've seen too. help? -Patrick
