Comment 52 for bug 1795453

With the 4.18.0-8-generic kernel, I see AMD IOMMU IO_PAGE_FAULTs for invalid addresses
AMD-Vi: Event logged [IO_PAGE_FAULT device=e1:00.0 domain=0x0000 address=0xfffffffffffd14c0 flags=0x0030]

PERC controller is still present btw, but the vdbench stress crashed due to this page faults.
