I've run some tests on an arm64 board using an USB to Ethernet adapter that uses the same driver (It also goes through ax88772_bind() ) but I don't reproduce the error.

The next step for me would be to try on an x86_64 box to get closer to the config you used, however could you give me the .config that was used when the bug was triggered ? I'd like to make sure I didn't miss anything related to some of the parts being build as modules for example.
Thanks a lot,
Maxime
