--- Comment #12 from Lothar Paltins lopa@mailbox.org --- I've got the same issue with an AMD Ryzen 5 2400G after a power cycle of the monitor (Dell U3011 with a resolution of 2560x1600 connected via DisplayPort). It happened not always, but very often. I thought, it was fixed by the workaround with the "drm.edid_firmware=..." kernel parameter, but now it happened again. And there also seems to be a crash in the amdgpu driver. I've attached the dmesg output after this happened.
