description |
In my PC i have 2 NICs, on eth0 i have a built-in NIC of an unknown brand/type and on eth1 i have a 3Com 3C900b-TPO.
Eth1 connect to the internet, eth0 is the LAN.
The problem is with eth1. Since my upgrade to Feisty "the internet" stops responding.
At first i thought it was a DNS issue, but discarded that idea after i've found that IP addresses outside my LAN couldn't even be pinged at that time.
I've tried restarting networking by executing "/etc/init.d/networking restart" but that didn't help.
Restarting the PC helped for a while, but that is hardly a solution to the problem since i am running a shoutcast server and an FTP server which i really want to keep available at all times.
I've found the following in /var/log/syslog:
[ 2442.499383] NETDEV WATCHDOG: eth1: transmit timed out

The times of these entries coincide with the times that the NIC stops responding.
The problems started after upgrading the kernel to 2.6.20. I'm currently running the 2.6.17 kernel without problems so i've ruled out the option of it being a hardware issue.
The driver used in both kernels is 3c59x, which suprized me since the 3c59x line was an ISA card and the 3c90x is a (non-wireless) PCI card. |

Bug seems to be related to having 2 NICs in one system.
