Can you post some more information about what NIC you are using
(brand, version, etc).
Also, output from 'lspci -v' should be helpful.
What PC are you using?
Are there any errors in /var/log/messages (or dmesg) before this
error?
In the past, it has been suggested that you try disabling power-saving
and see if that helps. If you do try this and it *does* help, please
let us know.
Thanks,
Ben
