Dear Christian,


Thank you for your reply.

not sure how the IOMMU gives out addresses, but the printed ones look suspicious to me. Something like we are using an invalid address like -1 or similar.

Can you try that on an up to date kernel as well? E.g. ideally bleeding edge amd-staging-drm-next from Alex repository.

These are production desktops, so I’d need to talk to the user. Currently, Linux 5.10.70 is running.


Kind regards,

Paul
