NETDEV WATCHDOG: eth0: transmit timed out

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Transmit timeout, status 00000004 00000249

This was the error that i got in my kernel log message.

I was unable to use internet in my laptop "MS 1006". I tried setting up the network in either way (dhcp and static) but non of these solved the problem. I got terribly wired, as i could see no other message beside "destination host unreachable" and waiting for never offering, DHCP.

I even wasted 2 days and even googled for many keywords. But i couldnt get the solution. But finally the end of the second day was fruitful. I solved it.

This was due to the interrupt conflict that occured between the acpi and network modules.
I turned off acpi while booting by adding following words at the end of the boot option.

Before:

title Ubuntu 8.04, kernel 2.6.24-16-generic
root (hd0,1)
kernel /boot/vmlinuz-2.6.24-16-generic root=UUID=e89b77d0-3183-4036-b508-15d9a23dc86c ro quiet splash
initrd /boot/initrd.img-2.6.24-16-generic
quiet

After:

title Ubuntu 8.04, kernel 2.6.24-16-generic
root (hd0,1)
kernel /boot/vmlinuz-2.6.24-16-generic root=UUID=e89b77d0-3183-4036-b508-15d9a23dc86c acpi=off ro quiet splash
initrd /boot/initrd.img-2.6.24-16-generic
quiet

Enjoy the net.
