В момент, когда NetworkManager пытается поднять интерфейсы, ядро ругается:

Если добавить в blacklist micrel, то интерфейсы успешно поднимаются с generic PHY:

Потому, что проблема наблюдается именно при использовании kernel-image-std-def из Сизифа. То есть понятно, что проблема внесена новой прошивкой Байкала, но на них, увы, можно повесить сколько угодно собак -- результат бывает далеко не всегда и всегда долго...

Нет. Проблема не зависит от версии прошивки. Я не вполне разобрался в особенностях байкаловского dwmac. И баг в драйвере был всегда. Я тестировал драйвер только с generic PHY. А байкаловцы взяли "мой" драйвер для 5.4 без изменений.
