Please post the output of > "ip link list <dev>". This is a bug in the qeth driver. It has been introduced by this commit: commit 3b04ddde02cf1b6f14f2697da5c20eca5715017f Author: Stephen Hemminger <shemminger@xxxxxxxxxxxxxxxxxxxx> Date: Tue Oct 9 01:40:57 2007 -0700 [NET]: Move hardware header operations out of netdevice. Since hardware header operations are part of the protocol class not the device instance, make them into a separate object and save memory. Signed-off-by: Stephen Hemminger <shemminger@xxxxxxxxxxxxxxxxxxxx> Signed-off-by: David S. Miller <davem@xxxxxxxxxxxxx> I've hacked up a fix for it. The real fix will be done by our networking people. -- blue skies, Martin.
