I recently bought this board as I wanted to start doing pci passthrough emulation.

I noticed that after I had installed it and booted up, with IOMMU enabled
the network would work fine for a while then I would get an AMD-Vi IO page fault 
and the driver would crash. 
IF I turn off IOMMU there is no problem with using ethernet,

The onboard ethernet chip is a RTL8111F/8168F.
For now I've turned off the network adapter in the bios and am using an add on card.

Then I noticed that I could not use the onboard audio with oss (4.2.2007) with IOMMU
enabled. Alsa works ok, but I prefer to use oss. As with the ethernet card if I turn off
IOMMU in the bios the onboard audio is recognized and works fine.

Any clues or help would be appreciated
Thanks, Don

I tried many setting on various config entries and finally found reference to using "iommu=pt" on the command line and it is working, at least for sound. I'll try the ethernet later to see if that problem is fixed.

Thanks, Don

Probably a missing IVMD block for the sound device.

The ethernet device issue could be a driver issue -- 
DMA write to a page that was mapped for read-only.
Providing the IO page fault message would help to
diagnose further.

Hi,

Would you please provide the kernel log and the dump of ACPI (from tools 
like "acpidump")?  These should help debugging the issue.

Thank you,
