Issues with booting when VT-D enabled

Hi people,

So today I decided to go back to Arch Linux. Installation went pretty well and didnt take too long.

After setting up stuff, I decided to go into the UEFI and turn VT-D on. I switched Arch back on again and it gave me a bunch of errors. Later it boots into my login manager but keyboard and mouse do not work. Disabling VT-D gets rid of these errors and the issue with keyboard and mouse.

But I want to use VT-D for qemu/kvm, but I honestly don't know what to do.

What I tried so far:

SSH'ing into my PC and ran: sudo mkinitcpio -p linux

This did not help.

edit:

Erorr is: fault reason 01 present bit in root entry is clear, and the device ID comes from the USB 3.0 controller. So IOMMU on Linux prevents my USB 3.0 controller to work.. But front panel USB do work though.
