Felix, thank you very much - this is exactly what I needed! Also now
found a "51192_Bolton_FCH_RRG.pdf" with slightly newer (but similar)

Dear friends, thank you so much for your kind help! Now this important
work is completed for G505S

Maybe we can fix the IRQs for some other AMD fam15h boards in a similar way.

Best regards,
Mike Banon
