Yes, I think also do_pio_read should be fixed. The two sides are slightly different: in the do_pio_write case, you loop forever, so the problem is instantly visible. In the do_pio_read case you loop until the word is complete. This should be okay in most cases, but I could imagine error conditions where this is no longer true and you'd end up with a system that dies from time to time. - Werner
