The patch seems to be good. After applying it, my UART passes the
modified test. I never tried enabling the interrupt twice, as your
modified test does, and was not aware that in this case my hardware
would raise an interrupt. How did you know? Can we be sure that possible
other UARTS affected by UART_BUG_TXEN will also do this?
thanks,
Thomas
