1 Hi !

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