NETDEV WATCHDOG: eth0: transmit timed out

Hi all

I got a problem with several ml350G4. Some time, when I execute a command which output a lot of text on the terminal emulator (putty), the nic gets disabled! In /var/log/messages I find:

Oct 17 12:39:27 sp02 kernel: NETDEV WATCHDOG: eth0: transmit timed out
Oct 17 12:39:27 sp02 kernel: Cannot get access to nvram interface!
Oct 17 12:39:27 sp02 kernel: bcm5700: eth0 NIC Link is Down

Thanks,

Try adding the noapic option to the kernel.

Edit the /etc/grub.conf and change the kernel options, something like this:

kernel /vmlinuz- root=LABEL=/ rhgb quiet noapic

Remember to just add the noapic option to the current options, do no change anything else. You need to reboot the server.

BY changing this "kernel /vmlinuz- root=LABEL=/ rhgb quiet noapic" - What will this do? Quiet or ignore the error? I do get a lot floating point errors when I type dmesg - What can I do for that? Sorry, if I jumped in on someone else topic with a different question. I am just trying to learn as much as I can with Linux OS.

Thanks,
Ian

See the kernel-parameters.txt available in the Documentation directory of the kernel source. You will get a description of the parameters that you can provide to the kernel.

noapic: SMP,APIC Tells the kernel to not make use of any IOAPICs that may be present on the system.

why do you think that there is a problem with apic?
