Not much detail in the bugzilla yet, but apparently this started in
v5.8.0-rc1:
DMAR: [DMA Read] Request device [03:00.0] PASID ffffffff fault addr fffd3000 [fault reason 06] PTE Read access is not set
Currently assigned to Driver/PCI, but not clear to me yet whether PCI
is the culprit or the victim.

Thanks for the heads-up, looks like Intel is already on it.
