NETDEV WATCHDOG: eth0: transmit timed out
 

Hi guys,
go easy this is my first post, got a few problems with one of my servers running kernal 2.4.18-14 Redhat 8, the machine seems to lock the network card, and make it inactive till it is rebooted this is happening every few days, ive look though google and your forums and all i could find was people who had the problem but no one seemed to have a definate answer on how to fix it so i thought id give posing a copy of my error a go.

We tried changing the network card as it seems like a network card error this did nothing to help it .

I get one of these messages at boot when a service tries to use the card soon after it has initialised.

I have found that it is happening while the card is still negotiating the 10/100 Mbps phase to the switch...

perhaps try netdev_max_backlog
 

I don't yet know if this will really help. I've encountered the same thing with one of my systems after an upgrade to a 2003 motherboard (Asus A7N266-VM w/ 2GHz Athlon) but with the same old 2000-era NIC (3c59x). If kernel tuning doesn't solve it, I'm ready to replace the old NIC soon. But here's what I tried for now...

I checked the netdev_max_backlog parameter and found it to be only set for 300. While that should be able to handle up to 30MBytes/sec (which is more than 100Mbits/sec), it doesn't leave a lot for a backlog, which may be what's causing the driver to freeze.

I've tentatively tried this...
echo 3000 > /proc/sys/net/core/netdev_max_backlog
I did that once as root interactively to set it in the running system, and added it to /etc/rc.d/rc.local so that it'll be done again upon boot. Now we wait and see if the problem goes away or not. If it didn't solve it, I should know (with another network halt) within a couple days. Meanwhile I'll keep looking at Google and also scan for other tunable parameters which may be candidates.

Nevermind (netdev_max_backlog)
 

It didn't help. In my case, Google leads me to conclude from others' experiences that this problem is because of the old 3c59x card or its driver, and is triggered by extreme bursts of traffic. Since the kernel tuning didn't help, I'll replace the card today. (This was probably always a risk with this driver but my older CPU/motherboard weren't able to stuff enough data onto the card so that it couldn't keep up.)

If you have the same card, then maybe this was still of some help to you. If not, sorry for bringing up false hope about this.

NETDEV WATCHDOG TIMEOUT
 

I too am getting these errors on my network card Realtek 8139c. At the first install of FEDORA core 1 everything worked. After that the second boot onwards the card gives me the following errors. I am including the output of dmesg, lspci and /proc/pci for reference. Can anybody help me on this???

I have tried giving "noapic" to grub at the command line . Also switched off apic at BIOS level but this problem is still occuring.

Thanks.

this helps
 

It worked for me after days of searching!

let me know please if it helped you to....

82573(V/L/E) TX Unit Hang messages
Several NIC's with the 82573 chipset display “TX unit hang” messages during normal operation with the linux e1000 driver. The issue appears both with TSO enabled and disabled, and is caused by a power management function that is enabled in the EEPROM. Early releases of the chipsets to vendors had the EEPROM bit that enabled the feature. After the issue was discovered newer adapters were released with the feature disabled in the EEPROM.
You can test whether your system is affected by this bug using the script found on the Tx Unit Hang page.
If you encounter the problem in an adapter, and the chipset is an 82573-based one, you can verify that your adapter needs the fix by using ethtool:
# ethtool -e eth0
Offset Values
------ ------
0x0000 00 12 34 56 fe dc 30 0d 46 f7 f4 00 ff ff ff ff
0x0010 ff ff ff ff 6b 02 8c 10 d9 15 8c 10 86 80 de 83
^^
The value at offset 0x001e (de) has bit 0 unset. This enables the problematic powersaving feature. In this case, the EEPROM needs to read “df” at offset 0x001e.
A one-time EEPROM fix is available as a shell script. This script will verify that the adapter is applicable to the fix and if the fix is needed or not. If the fix is required, it applies the change to the EEPROM and updates the checksum. The user must reboot the system after applying the fix if changes were made to the EEPROM.
Example output of the script:
# bash fixeep-82573-dspd.sh eth0
eth0: is a "82573E Gigabit Ethernet Controller"
This fixup is applicable to your hardware
executing command: ethtool -E eth0 magic 0x109a8086 offset 0x1e value 0xdf
Change made. You *MUST* reboot your machine before changes take effect!
The script can be downloaded here (fixeep-82573-dspd.sh).

I really doubt this thread is even relevant now, it was started in 2003 and any problems extant then are likely to no longer exist.

It's relevant to me. I have several production servers built ca. 2003 and one of them just threw this error. Since the machine is otherwise performing well, I would rather replace or tweak a card than build a whole new machine.
