>Number: 5347 >Category: kern >Synopsis: DEC (de0) ethernet card has no buffers after cable reset? >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Fri Dec 19 15:40:01 PST 1997 >Last-Modified: >Originator: David Gilbert >Organization: Velocet Communications >Release: FreeBSD 2.2.5-RELEASE i386 >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?
