Bug ID: 108322 Summary: RX580 Display flickering after waking from suspend Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: bmilreu@gmail.com
GPU RX580 Nitro+ over DisplayPort to a single AOC 75hz monitor. Issue is on last kernels 4.18 4.19 but not in 4.14.
Screen starts flickering until reboot if I sleep/wake or if I manually switch the monitor off/on.
Tried to turn amdgpu.dc=0, screen then flickers everywhere anytime unless I manually change frequency from 75hz to 60hz. That only solves it inside KDE though.
Checking gpu related logs shows this error, but couldn't find anything else: "Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff"
