Created attachment 277359 --> https://bugzilla.kernel.org/attachment.cgi?id=277359&action=edit dmesg 4.18-rc4
Since 4.18-rc1 I get following messages in dmesg:
[ 3.139281] kfd kfd: DID 15dd is missing in supported_devices [ 3.139282] kfd kfd: kgd2kfd_probe failed
No errors with 4.17 and 4.17.5.

After bisecting it seems this was introduced in:
