When booting kernel 4.17 or 4.18-pre on Power9 machine with Radeon Pro WX 4100 I get no output on a monitor connected thru DisplayPort, the monitor is not detected by the driver and a "PowerPlay" error appears in the kernel log. When booting 4.16 kernel (kernel-4.16.16-300.fc28.ppc64le), all is OK. See attached dmesg (resp. journalctl -k -b) outputs.
