--- Comment #9 from Chris Bainbridge (chris.bainbridge@xxxxxxxxx) ---
The IOMMU error is caused by a buggy VL805 firmware. It is more visible with
the Debian kernel as Debian patches the kernel to enable IOMMU by default. The
updated firmware can be installed using the VIA Windows tool (this did not work
for me), or you can just turn off IOMMU.
