I can check, but still, it's a regression in the Linux driver - old kernel did work perfectly well on this hw. Maybe new driver tries to use some feature that is missing (or broken) in the old firmware? > Also, you mentioned that on another system this issue doesn't reproduce, = do > they have the same firmware version? The other one has also 1.1-4 firmware. And I re-checked, e1000e from 6.14.2 works fine there. --=20 Best Regards, Marek Marczykowski-G=C3=B3recki Invisible Things Lab --FtZpEP7ZV9KwPWkb Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEhrpukzGPukRmQqkK24/THMrX1ywFAmgGRdAACgkQ24/THMrX 1yxLeAf8DvKL+foWSoIwDphGGhQZ3unGbl5ca72JDBQ6KcM6JxaNauYhY9mpzz+C ZESupbqixbb+HLmbIbEQLVlDyfxAW6x6y4sBV+8c3fy8678Z+c2PcHIgiX8YV0a1 Ntrjn9GRZBWi2e6RmJSCHijHtRlfQsjDxSWiwT1WxjuNVROgsLOW9LXPZmXvasnp UDTqgIhH6jcNFhaQ/pQcoGyZ31vG6pVLeloePXDOlJ35Gb+4Cts6jTeqBxxyF0R8 O1TMVSAYc3G6wlH7o1eSQ4pLeORMY0H8m/kf1dMOLj7osPorfDauk5KLXVm2WWJh VEKHuDwHUdeCHvG8BvsOAKR9tsuung== =gE/2 -----END PGP SIGNATURE----- --FtZpEP7ZV9KwPWkb--
