--- Comment #7 from Felix Kuehling <felix.kuehling@amd.com> ---
Good timing. We were just given a laptop that has similar problems and found a
partial workaround: Try adding "iommu=pt" to your kernel command line. This may
at least get you through the KFD initialization, but there are likely more
problems down the line.

The problems are due to BIOS bugs. We're looking into more workarounds to
ignore or patch incorrect information in the CRAT ACPI table that describes the
compute devices for KFD.
