Thanks, the rest of the log file looks fine.

The above warning and error messages indicate that drmModeAddFB fails.
Since you got the "Failed to make prime FD for handle" error message
from glamor with the 18.0.1 driver, there might still be an issue
related to the GEM handle of the front buffer.

I've never seen this before, so I suspect it could be an issue specific
to NetBSD's KMS support. Can you poke around a bit to see why
drmModeAddFB fails? E.g., what are the parameters passed to it by
radeon_fb_create, and what error does it return?
