It already starts, with that patch I am getting:
xhci_hcd 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000f address=0xff00ffffffefe000 flags=0x0000]
In my kernel log. The device is an AMD XHCI controller and seems to
funciton normally after boot. The message disappears with
iommu.forcedac=0.
Need to look more into that...
