SubjectRe: IOMMU+DMAR causing NMIs-s
Getting back to an issue after more than a month of summer.

Tested on 4.6.0 with hpwdt off.

On most boots, nothing strange happens. Got some NMIs (below). Usually it's
during the radeon startup but in slighlty varying places, and the address
varies: 1000 2000 3000 9000 a000 b000.

Got also a hang after radeon startup:
