如何在啟動時刪除 acpi 警告？

我在dmesglinux 3.11.6-1 (2013-10-27)（debian 版本）的日誌中有此消息。

我想知道如何修復/刪除它？

此消息是關於某些驅動程序被拒絕訪問由ACPI控制的設備。

總的來說，我的經驗是可以放心地忽略它。但是，如果您真的堅持要刪除警告，我建議您不要嘗試使用選項 acpi=off 啟動，或者您可能只嘗試一次以查看會發生什麼。但我擔心你可能會發現你在使用 wifi、藍牙時遇到了麻煩……但是這裡他們說這大多是無害的，所以嘗試一下也無妨。

修復它的一種可能方法是使用該選項啟動

processor.nocst=1

它介紹了與一些舊 ACPI 軟體的兼容性，請參見此處。另一種方法是使用該選項

acpi_enforce_resources=lax

這顯然允許載入驅動程序。這可能會或不會干擾 ACPI 操作。

只是為了完整起見（如果您已經知道這一點，請道歉），引入這些修改，編輯 /etc/default/grub 並替換

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" 

和

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" 

或您決定嘗試的任何選項。更新grub，重啟。
