I can't start ubuntu and mint, because it fails with the error:

Unexpected IRQ trap at vector 07

I'v tried ubuntu 17.04 and mint 18.3 (based on ubuntu 16.04).

My processor: AMD Ryzen 1500x
My motherboard: ga-ab350m-d3h

I tried to update my bios from F1 version to F3 one, but it didn't help me. Also I didn't find acpi in my bios.

Any ideas?

  • Thank guys! The problem solved by installing ubuntu 16.04.1
