Could you please double check if IOMMU is enabled?
Have you tried to disable it? Does it make any difference?
No idea how. UEFI doesn't seem to show anything similar.
Similar bug report: https://bugzilla.kernel.org/show_bug.cgi?id=202241
As mentioned in that bug report, adding "iommu=off" to the kernel
command line will disable it. I think there's also an "iommu=soft"
option, but I'm not sure what that does.
