Thanks for the response, Bastian!
I have been using this option since kernel 4.15, when the AMD Display Code was
merged. Without these options the card
would panic and the system would crash.
Kernel 4.17 and 4.18 finds and load the firmware without problems and the
system is stable.
Here is a part of /var/log/syslog booting from kernel 4.18 and using

The firmware is there and is loaded on kernel 4.18 but not on 4.19.
Any idea on what I should try?
