Bug ID: 103271 Summary: AMD R9 270X Flickering with DPM Enabled on Linux 4.1 with RadeonSI Product: Drivers Version: 2.5 Kernel Version: 4.1.6 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: wittyman37@yahoo.com Regression: No
I upgraded my system today from the 4.0 kernel to 4.1. After rebooting, I am getting crazy flickering that makes my system unusable. I rebooted and disabled dynamic power management with radeon.dpm=0 as a kernel parameter. The flickering is now gone. I have an R9270X running with the open source drivers. I did a quick search and could not find a similar issue anywhere. Does anyone have any suggestions?
UPDATE: I built the kernel using the linux-git package in AUR and have the same issue with DPM. linux-git 4.2rc7
