[vfio-users] New motherboard, vt-d broken

[francesco dicarlo]

Hi to all,
I've replaced a B85M-HD3  Rev2 Motherboard with a recent Asrock
H97-Anniversary...

System was working flawless with windows 8.1 and ovmf...

Now I'm greeted in dmesg with a bunch of this errors,

   60.217761] dmar: DRHD: handling fault status reg 3
[   60.217763] dmar: DMAR:[DMA Read] Request device [01:00.0] fault addr
be1e5000
               DMAR:[fault reason 12] non-zero reserved fields in PTE

Booting windows leads to a common Code 43...

The only 2 devices attached to vfio-pci are gpu and gpu sound hardware...

Should I try a different bios? What should I inspect?

Regards
