Что-то сетевая карта прикалывается или wifi карта.

[Cramac]

а что мудрит сетевая? стоит двухпортовая встроенная и двухпортовая отдельная.
Единственное что смущает в них, после ребута, меняются имена местами.

[AlexBKost]

Cramac, если я не ошибаюсь, на 16.04 сейчас актуальным является ядро 4.4.0-78-generic (без обновления графического стека). Если обновление до этой версии не поможет, попробуйте параметр acpi=off для загрузки ядра. Обычно помогает от сваливания в kernel panic.

[Cramac]

У меня остановилось на 4.4.0-66
дальше предлагает только релиз обновить до 16.10

заодно отключил acpi посмотрим что будет.
