I will leave NEWLY_ATTACHED and HAS_BEEN_RESET alone. On bisect: the status register is read before the condition is evaluated, so no version of that test can change the value =E2=80=94 bisecting the dri= ver would read the same thing throughout. What differs is the machine, two months apart, and I cannot recreate July to walk between them. So it stays unexplained, and by your account it does not need to be: only NEEDS_INITIALIZATION matters, and first_hw_init OR the bit is what the driver now does. Sergey
