I can confirm that the iommu=pt workaround works, also iommu=soft works to get gdm started and use the laptop. Sadly i have no idea what impact those workarounds have when it comes to performance of the gpu/cpu or battery lifetime ?
Sadly i had a freeze during desktop usage shortly after boot using iommu=pt. The driver situation for raven ridge is really sad atm :( .
