我刚刚在加载 Ubuntu 时在笔记本电脑屏幕上看到了以下错误消息,但我能够毫无问题地登录。你认为这里可能出了什么问题?
DMAR: [Firmware Bug]: No firmware reserved region can cover this RMRR [0x000000008d800000-0x000000008fffffff], contact BIOS vendor for fixes
DMAR: [Firmware Bug]: Your BIOS is broken; bad RMRR [0x000000008d800000-0x000000008fffffff]
我在内核日志中找到了更多详细信息:
BIOS vendor: INSYDE Corp.; Ver: 5.00; Product Version: PSLZAE-00R00STE
DMAR-IR: IOAPIC id 2 under DRHD base 0xfed91000 IOMMU 1
DMAR-IR: HPET id 0 under DRHD base 0xfed91000
DMAR-IR: x2apic is disabled because BIOS sets x2apic opt out bit.
DMAR-IR: Use 'intremap=no_x2apic_optout' to override the BIOS setting.
DMAR-IR: Enabled IRQ remapping in xapic mode
x2apic: IRQ remapping doesn't support X2APIC mode
