Well, I tried 2.4.22, the change is really small:

...to no avail, the problem persists. However, there is a funny
thing I observed: the driver still logs the *same* error message¹
to the ringbuffer when I do even byte transfers, however for some
weird reason the driver reports success, and lo, I can read the
file back and it is intact. Odd byte transfers trigger the same
condition and the driver reports no sense. Very strange...
