I built and tested Linux 5.8.18, with the same firmware, and it is working correctly. I reduced the test case to just rfkilling the connection, which showed the register dump immediately (before that I was using the airplane toggle on the keyboard, which isn't working correctly, it disables and immediately reenables the radio, for some unfathomable reason). So, now I'm inclined to believe this is some sort of race condition between rfkill and pending transactions. Thanks, Rui
