Current panic on boot on H11DSI motherboard with epyc cpu (nexus_add_irq: failed)

Yep. That it.

But just one note 

irq585: ccp14:721 @cpu0(domain0): 0
irq586: ccp14:723 @cpu0(domain0): 0
irq587: ccp15:725 @cpu0(domain0): 0

If I understand correctly number of irq's even more then 512, so better to change to real number in system ?

Or this is another case ?

Any way thank you for help. Now I can use system with msix and msi enabled.
