Buggy AMD-Vi firmware and patches?

Every time I start enabling IOMMU and virtualization options I get crashes and strange errors:

:: Code ::
Jan 23 14:33:21 ronin kernel: [Firmware Bug]: AMD-Vi: IOAPIC[9] not in IVRS table
Jan 23 14:33:21 ronin kernel: [Firmware Bug]: AMD-Vi: IOAPIC[10] not in IVRS table
Jan 23 14:33:21 ronin kernel: [Firmware Bug]: AMD-Vi: No southbridge IOAPIC found
Jan 23 14:33:21 ronin kernel: AMD-Vi: Disabling interrupt remapping

I don't have the knowledge to track down these errors to their sources, but the internet seems to be saying it has to do with buggy firmware.

I gave up messing with this but now I've got something in the log asking for the 64MB IOMMU option, and several installed programs needing virtualization functionality.

I can't understand the problem or the solution, but I've seen some patches and workarounds. Would it be possible to put any of these in Liquorix? There also seem to be kernel boot options that will help.

Here's stuff I found:

5/28/13: Kernel boot options - but I read something suggesting this wasn't secure or optimal.


4/9/13: Patch from Joerg Roedel



Link to ASUS forum thread which I can't read because it's down:


12/2/13: Seemingly weakly related patch

Okay, I discovered AMD has been regularly releasing BIOS updates for my MB, which fixed this problem.

So, I suggest anyone with this problem to update their BIOS to see if that fixes it.

I'm glad to have that out of the way, but sorry for the noise.
