[Intel-wired-lan] issue with kernel patch 2a3cdead8b408351fa1e3079b220fa331480ffbc

[Jochen Henneberg <jh@henneberg-systemdesign.com>]

Hi Todd,

I have send all background information to Kontron (FAE), they will take
a look if the BIOS somehow communicates with the external NIC.
The FAE told me that he does not want to join the mailing list, so I
will exchange the information from/to Kontron off-band and push them to
the list if I get updates.

Regards,
Jochen
