Uh oh, OK.

Is this a regression compared to current official Tails releases?

Could you please retry with the latest USB image (.img) from

https://nightly.tails.boum.org/build_Tails_ISO_feature-6560-secure-boot/lastSuccessful/archive/build-artifacts/

And add this boot option when starting Tails:

    intel_iommu=off
