dmesg我在linux 3.11.6-1 (2013-10-27)（debian 版本）的日志中看到此消息。
我想知道如何修复/删除它？

答案1
此消息是关于某些驱动程序被拒绝访问由ACPI。
总的来说，我的经验是可以放心地忽略它。但是，如果您确实坚持要删除警告，我建议您不要尝试使用选项 acpi=off 启动，或者您可以尝试一次看看会发生什么。但我担心你可能会发现你在使用 wifi、蓝牙时遇到了麻烦，......但是这里他们说这基本上是无害的，所以尝试一下也没什么坏处。
修复它的一种可能方法是使用选项启动
processor.nocst=1
其中介绍了与一些旧 ACPI 软件的兼容性，请参阅这里。另一种方法是使用该选项
acpi_enforce_resources=lax
这显然允许加载驱动程序。这可能会或不会干扰 ACPI 操作。
只是为了完整起见（如果您已经知道这一点，抱歉），要引入这些修改，请编辑 /etc/default/grub 并替换
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
和
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
或您决定尝试的任何选项。更新grub，重启。
