the last error is, IME, machine-specific.  there's a class
of radeons that fail on my ryzen 5600G, but not a ryzen
3950X or ryzen 3600.  i've seen the failure with 5450,
6340, and an R240 (just like you :-), but all those cards
work fine in the 3600.  the same physical card, not just
the same model.

eg, PR#56714 has this line in it:

kern error: [drm:([...]radeon_r600_dma.c:274)r600_dma_ring_test] *ERROR* radeon: ring 3 test failed (0xCAFEDEAD)

that i believe is the same error (though ring 0 above is
less common, mostly i see ring 3, but it's the same test
being performed.)

fortunately, the 5600G is fast enough that most of the
time i don't care about the lack of accel... :-)
