>Environment:
I have two cards de0 and de1. They are from Kingston technologies
and probe as follows:
de0 <Digital 21140A Fast Ethernet> rev 34 int a irq 9 on pci0:10
de0: 21140A [10-100Mb/s] pass 2.2
de0: address 00:c0:f0:17:1d:5a
de1 <Digital 21140A Fast Ethernet> rev 34 int a irq 12 on pci0:12
de1: 21140A [10-100Mb/s] pass 2.2
de1: address 00:c0:f0:17:39:3e
>Description:
de1 is plugged into a hub, so it never has a problem. de0, however,
is plugged into a linux box (crosover cable, 100Mb full-duplex)... and
exhibits the problem --- if the linux box reboots, then pinging the interface
will produce a no buffers error. ifconfig down followed by ifconfig up
fixes this. Here's the ifconfig -a:
de0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
ether 00:c0:f0:17:1d:5a
media: autoselect (100baseTX <full-duplex>) status: active
de1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 206.108.246.85 netmask 0xffffff00 broadcast 206.108.246.255
ether 00:c0:f0:17:39:3e
media: autoselect (10baseT/UTP) status: active
>How-To-Repeat:
Connect as described, reboot linux box.
>Fix:
run ifconfig down followed by ifconfig up every 10 min?
