In particular, the following problem can happen (shown for a TurboPMAC,
but MasterMACS will run into the same issue):
2026/03/31 11:45:04.698 asynPortDriver:getDoubleParam: port=turboPmac1 error getting parameter 42 MOTOR_STATUS_HOMED, in list 1, wrong type
2026/03/31 11:45:04.698 Controller "turboPmac1", axis 1 => virtual asynStatus turboPmacAxis::init(), line 168:
Accessing the parameter library failed for parameter motorRecResolution_ with error wrong type.
This is definitely because of 7.4.0, because forcing 7.3.2 fixes it.
