Re: IPC2 serial ports...

The middle one (n°2) is the one which don't works.
We managed to make 1 and 3 working with the mentioned tricks (UEFI boot + forcing IRQ setting after auto-detection for one of the ports).
We are sending a lot of data on these serial ports, so we need the IRQ to works well. With simple tests with a terminal, all ports seems to works because they are falling back to polling. But polling performance is not enough for our application.
