I plugged in the tg3 to a e1000 (via cross-over cable), and then, or very soon after that, the machine hung solid (or, maybe it tried to spew to console..was on kvm and not selected..) Last thing I see in the /var/log/messages is tg3 saying flow control is on for tx and rx. Now, it could be one of a million things...but just curious if anyone else has seen anything like this. Kernel is 2.4.20 + my hacks. Take it easy, Ben -- Ben Greear President of Candela Technologies Inc http://www.candelatech.com ScryMUD: http://scry.wanfear.com http://scry.wanfear.com/~greear
