Created attachment 139779 [details] journaltcl log file for linux-amd-staging-drm-next I was able to compile the "amd-staging-drm-next" tree with the help of a small patch (https://github.com/StuntsPT/linux-amd-staging-drm-next-git/blob/master/PKGBUILD#L50) as of commit "46c04bb3e028217255b578cc6101823e9fbc11bc". However, using this kernel I can never get a successful boot (10/10) failures. I have attached the journalctl log for one of these failed boots. I hope this helps.
