Re: [gentoo-user] packets with bad cheksum

Hi !

If by any chance you are using the 8139too driver with 2.6.8.1 ...
drop it. This driver is horribly broken and has been flagged as so in
the lkml. It has been fixed in the 2.6.9 series and the problem is not
found in the 2.6.7 series since this comes from a patch that was
merged in the 2.6.8.1

Cheers !

Jean-Francois
