Ubuntu 16 Kernel BUG ("Упс: 0000 [#1] SMP") связано с amdgpu

Я недавно установил Ubuntu 16.04 на свой персональный ноутбук (Dell Inspiron 5548), и каждый раз, когда я пытаюсь выйти из любой учетной записи пользователя, я получаю сообщение об ошибке Kernel ("Ой"), связанное с amdgpu.

Я пробовал как обновить 14 LTS, так и полную установку, используя образ 16.04 на USB-диске. Я также использую Ubuntu 15 на своем компьютере довольно долго без каких-либо подобных проблем.

Я читал, что это может быть связано с заменой fglrx новых графических карт amd и что будут поддерживаться только новые графические карты. Тем не менее, я установил Ubuntu 16 на Dell Studio 1458 (графическую карту сейчас не помню, но это тоже Radeon), и она работала как шарм.

Сообщение об ошибке следует ниже. Кто-нибудь знает какое-нибудь решение для этого?

РЕДАКТИРОВАТЬ: моя видеокарта AMD Radeon™ HD R7 M265.
