Hi,
I have mb MSI A88X-G43 with latest bios version.
This error messages at startup:

    0.013304] [Firmware Bug]: AMD-Vi: IOAPIC[0] not in IVRS table
    0.013309] [Firmware Bug]: AMD-Vi: No southbridge IOAPIC found
    0.013310] AMD-Vi: Disabling interrupt remapping

in dmesg:

linux-srv:~ # dmesg | grep AMD-Vi
    0.013304] [Firmware Bug]: AMD-Vi: IOAPIC[0] not in IVRS table
    0.013309] [Firmware Bug]: AMD-Vi: No southbridge IOAPIC found

    0.690155] AMD-Vi:  Extended features:  PreF PPR GT IA
    0.696809] AMD-Vi: Lazy IO/TLB flushing enabled

I have found this info.

I have booting with amd_iommu_dump=1 option in GRUB_CMDLINE_LINUX_DEFAULT and I got this result:

linux-srv:~ # dmesg | grep AMD-Vi

The ivrs table is wrong, how i can correct it with commandline in grub, ivrs_ioapic [HW,X86_64] ?

Thanks
