--- Comment #2 from andreas...@web.de ---
Reintroducing iommu=pt does, indeed, seem to fix these graphical issues. Why is
this flag suddenly required for proper operation again?
Is every laptop with an Raven Ridge APU different here or why can the kernel
not just figure out how to properly configure the IOMMU so that everything
works?
