Ethernet Aquantia AQN-107 does not work with 4.15.0-15-generic #16~16.04.1-Ubuntu SMP

[Andre Schlegel]

After upgrading to new kernel image:

Linux 4.15.0-15-generic #16~16.04.1-Ubuntu SMP Thu Apr 5 12:19:23 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Description: Ubuntu 16.04.4 LTS
Release: 16.04

The aquantia driver (Asus XG-C100C 10G NIC card) is loaded but does not work as expected (link state not detected by software):

Ping to its own address works.

Ping to the other end of the ethernet cable failed.

Booting the previous kernel image:

Then the link state is detected and everythink works fine:

Status changed to 'Confirmed' because the bug affects multiple users.

[Po-Hsu Lin (cypressyew)]

Hello,
do you still have this issue with the latest linux-hwe-edge kernel?
Thanks

[Andre Schlegel (andre-schlegel)]

Testing with:

Linux baufix 4.15.0-51-generic #55~16.04.1-Ubuntu SMP Thu May 16 09:24:37 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I don't have any issues at the current kernel. The bug is gone away. Thank you for your support.
