Всем привет. В общем, у меня не хватает знаний понять, кто же именно тут падает. Имеем следующее:

Это на Lenovo G580, Slackware64-current (с ядром 5.4.39, хотя наблюдается это уже давно). Система вроде бы и работает, но этот кусок лога напрягает. Кто что может подсказать?

[bormant]

Судя по дампу, падает в i915, но не фатально.
drivers/gpu/drm/i915/display/intel_display.c:16037 intel_modeset_init+0x17c9/0x1bf0 [i915]

Кстати, на то, что с драйверами видео от Intel делают что-то не то ,жалуются уже довольно давно...

[yars]

Хм, ну, раз с этим уже черти сколько никто ничего не пытается сделать, остается оставить как есть. Спасибо!

[bormant]

Так то оно значится пофикшеным:
https://bugs.freedesktop.org/show_bug.cgi?id=105992

Если точнее, рецепт известен аж с 26.04.2018:

Да, но каждый раз пересобирать nouveau лениво
И, по ссылке про баг пишут, что патч слили в master, разве нет?
