Hello,
adding nosmp pci=noacpi results in same behaviour - linux can't assign irq to usb&sata controllers(but I don't see IRQ >15 anymore). Adding nosmp pci=biosirq,noacpi allow system to boot.

I can reproduce this bug on Biostar AM1ML. I think this bug is ACPI related, if i add 'nosmp acpi=off' Ubuntu boots fine.
Hi
Parameter 'nosmp' disables I/O APIC and enforces PIC IRQ routing. How about 'nosmp pci=noacpi', it's less intrusive than using 'acpi=off'.
It is somewhat well-known that AGESA boards' IRQ routing is a one sick puppy [1] [2]. Or perhaps the entire litter, pun intended.
