> sio1: configured irq 3 not in bitmap of probed irqs 0
I would assume it means that 0x00000000 is the bitmap of probed irqs and that
irq3 0x10 configured for sio1 is not in that bitmap.
isa/sio.c:
/*
* Turn off all device interrupts and check that they go off properly.
* Leave MCR_IENABLE alone. For ports without a master port, it gates
* the OUT2 output of the UART to
* the ICU input. Closing the gate would give a floating ICU input
* (unless there is another device driving it) and spurious interrupts.
* (On the system that this was first tested on, the input floats high
* and gives a (masked) interrupt as soon as the gate is closed.)
