Comment # 12 on bug 105046 from Lothar Paltins

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.
