Ok. I'll check on parameters when I get spare time. I did consider such things could be part (all? :) ) of the issue.

Yet compiling such working drivers would either lead me to revert to an older kernel version (and not provide testing with newer ones, thus) or adapt the marvell driver to newer kernel, task which I'm rather not sure to be able to carry by some quite good amount of time :) You didn't brush me off, I wasn't expecting a straight working solution :) TFYA, --=20 Beno=EEt --a8Wt8u1KmwUX3Y2C Content-Type: application/pgp-signature; name="~/.gnupg/public_key.txt" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkqPJfYACgkQqNn0jQsEC2bwCgCeOWNfnCQD0lXVEyFeAk868pem aLEAn1cB5ujfeBwp/AzVqiVZMF0pXDqa =yM+X -----END PGP SIGNATURE----- --a8Wt8u1KmwUX3Y2C--
