Comment # 4 on bug 1189762 from Dainius Masiliunas

@Takashi: Yes, 5.13.12-lp153.7.gd66b4c0-default works correctly without any
kernel options!

@Joerg: Do you mean without any options on 5.3.18-59.19.1? In that case, no, it
literally freezes while showing the GRUB "Starting initial ramdisk..." line,
i.e. there is no video output at all. With acpi=off I would be able to see
where it freezes, but is that useful? With iommu=off or iommu=soft it does not
freeze. With all other iommu options it does not produce any output, just like
if I pass no iommu options at all.
