Ubuntu 22.04（内核6.2.0-33-generic）下ACPI BIOS错误无法隐藏的问题咨询

我的情况 #

刚装了台新机器，配置如下：

• 主板：Asus TUF GAMING B760M-PLUS
• CPU：i5-13600k
• GPU：Nvidia RTX 3060
  安装Ubuntu 22.04（内核6.2.0-33-generic）后，开机时弹出一大串ACPI错误日志。这些错误看起来没什么实际危害，但看着闹心，想把它们隐藏掉。

已经尝试过的方法 #

• 按照论坛常规操作，在/etc/default/grub的启动参数中添加loglevel=3，执行sudo update-grub后无效；甚至把日志级别调到0也压不住这些错误
• 试过acpi=off：直接无法开机，放弃尝试
• 还测试了pci=noacpi、acpi=force这类常见ACPI参数，均无效果
• 已将BIOS更新到最新版本，且关闭了Secure Boot

错误日志（dmesg | grep -i "acpi"输出） #

我的疑问 #

虽然这些错误不影响使用，但我实在搞不懂为什么论坛上大家都在用的loglevel=3方法在我这儿完全没用，有没有大佬能给点思路或者其他解决方案？

针对这个问题的建议 #

首先看日志里明确标了ACPI BIOS Error (bug)，这说明是华硕主板BIOS本身的ACPI定义问题——具体是GPU对应的ACPI方法_DSM在创建对象时重复了，属于BIOS层面的小bug，和系统本身关系不大。

至于loglevel=3没用，大概率是这些错误属于早期启动阶段的输出，常规的loglevel参数覆盖不到这个阶段。可以试试下面这些方法：

1. 更全面的启动日志参数
   编辑/etc/default/grub，把GRUB_CMDLINE_LINUX_DEFAULT改成：

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3 rd.systemd.show_status=auto rd.udev.log_level=3"
   

   然后执行sudo update-grub重启试试。这个组合能同时控制内核、systemd和udev的日志级别，覆盖更多启动阶段。

2. 调整ACPI兼容性参数
   试试在GRUB参数里加acpi_osi=! "Windows 2020"或者acpi_osi=Linux，这两个参数会让系统告诉BIOS自己是Linux系统，而非Windows，可能能避开BIOS里针对Windows的重复ACPI定义。修改后同样要执行sudo update-grub重启。

3. 检查Nvidia驱动
   你的RTX3060建议安装官方闭源驱动，而非默认的nouveau开源驱动——部分ACPI的_DSM方法是和GPU厂商驱动交互的，换驱动可能缓解这个问题。可以直接执行：

   sudo ubuntu-drivers autoinstall
   

   安装完成后重启系统看看效果。

4. 等待BIOS更新
   虽然你已经更到最新BIOS，但华硕后续可能会发布修复ACPI定义问题的版本，可以多关注一下主板官网的BIOS更新。

最后说句实在的，这些错误真的只是BIOS层面的小bug，完全不影响系统稳定性，如果以上方法都没用，其实也可以直接忽略，后续内核或BIOS更新后大概率会自动修复。
