I unfortunately don't have a public bug reference to share. This will impact PCIe based Intel hardware like DG1. The DRM support is quite recent for these, so in practise this only affects 5.15-rc and newer. And even on these, the functionality will be ok, it's just the warnings that fill the kernel log that are a problem. Br, Kai
