Hi, As Kyösti pointed, MP tables and IRQ is broken on AGESA boards. Most of the mainboards have mindlessly copy-pasted code that generates MP tables and IRQ tables. Those often contain entries of non-existing devices as a result. Since the most preferred way of IRQ routing is ACPI and most systems use it, the "noacpi" path wasn't thoroughly validated.
I will start working on it soon (most likely together with Kyösti), so the situation should improve a little bit.
