LinuxQuestions.org - NETDEV WATCHDOG: eth0: transmit timed out

Hoi list,

Everytime my laptop starts up the ethernet device, it first times out, goes down and only then comes up again with a good connection. Below is the output of /var/log/messages (with IP addresses removed).

Code:

13:39:59 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67

13:40:00 kernel: b44: eth0: Link is up at 100 Mbps, full duplex.

13:40:00 kernel: b44: eth0: Flow control is on for TX and on for RX.

13:40:02 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67

13:40:08 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67

13:40:10 kernel: NETDEV WATCHDOG: eth0: transmit timed out

13:40:10 kernel: b44: eth0: transmit timed out, resetting

13:40:11 kernel: b44: eth0: Link is down.

13:40:13 kernel: b44: eth0: Link is up at 100 Mbps, full duplex.

13:40:13 kernel: b44: eth0: Flow control is on for TX and on for RX.

13:40:20 dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8

13:40:21 dhclient: DHCPOFFER from <some IP address>

13:40:21 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67

13:40:21 dhclient: DHCPACK from <some IP address>

13:40:21 NET[10862]: /sbin/dhclient-script : updated /etc/resolv.conf

13:40:21 dhclient: bound to <some IP address> -- renewal in 710 seconds.

As a result of this the laptop keeps the localhost.localdomain hostname, and I have to login, do a killall dhclient and a service network restart, logout and login again. I find this pretty annoying.

If I recall correctly, this problem started a couple of months ago, probably when I upgraded my FC4 kernel with yum.

Any ideas on how to solve this are greatly appreciated.

Kind regards,
Regulus
