You need to rebuilld drm-510-kmod (for 13) or drm-515-kmod (for 14) by
hand from the ports (you need /usr/src installed for that). Binary
builds are done on different OS version and does not match your kernel
version - they would either wont load with error or cause kernel
panic. This is a known issue easy to fix.

I am on the 13.3 right now with hand built drm-510-kmod on RX580. Its
working rock solid. But on 14.0 with drm-515-kmod my machine was
unstable (known issue, frequent random panics due to
incompatible/missing LinuxKPI interfaces).

Someone mentioned that 14 branch can work with both drm-510-kmod and
drm-515-kmod. But I did not find that information nowhere in the
documentation before I reverted to 13 (from 14.0 with drm-515-kmod).
So if you could verify that 14.0 or 14.1 can work with 510 AND 515 drm
drivers and one of those drivers works fine for several days I could
move forward to 14 again :-)
