14,04 BIOS, Ошибки ACPI в dmesg

Я недавно обновляю с 12,04 x64 на ноутбук 14.04.1 x64 Dell Latitude

Я вижу сообщения в dmesg, которые вызывают меня беспокойство. Эти 2 выборки ниже - те, я больше всего обеспокоен в:

[    4.804950] i915 0000:00:02.0: irq 46 for MSI/MSI-X

ОБНОВЛЕНИЕ: Относительно сообщения BIOS я действительно на самом деле обновлял свой BIOS, и это решило вопрос.

Все еще ища справку на предупреждениях ACPI, если кто-то может указать на меня в правильном направлении....
