Hi all,

I have an issue with a remote server that keeps losing access to the
network. I've managed to replicate the issue by pulling a large file from
the server at full speed (100mbit). It will cut out during the file copy
and the log will show the following:

As it is remote I have to hard reboot it at this point to get anything more
out of it, something that I'm not too keen on doing too often.

From that I can work out there seems to be an issue with the sis900 card
but where to go from here I'm not sure on.

Any help would be greatly appreciated

Thanks

Oliver
