Dear AMD developers, I wanted to mention that the regression in amd-staging-drm-next which I reported on the 29.09. and the 06.10. still exists with the latest tree state of the branch. A crash/freeze occurs after the screen is re-enabled either from suspend or from screen locking (which shuts off the display as well). The system lock-timing varies: It can get stuck at a blank screen, at the login screen or even shortly after a login. The kernel is the unmodified amd-staging-drm-next running with my Tonga GPU. It does not occur in the official 4.13 kernel of Ubuntu 17.10. Unfortunately I failed to bisect it to the causing commit but the issue is there for a pretty long time in the 4.13 kernel, most likely merged into the code before 10.09. Did nobody else from this mailing list experience the same issue? Many regards, Martin
