I'll keep you updated.Hello,did you have any luck with the ASUS support.I should have the same ASUS Prime X370-Pro.
But when I enable IOMMU I am not able to boot, when the IOMMU is disable I have no problem to boot.I am on BIOS 0511 and kernel 4.10.5Tried with 0502, 0504 & 0511 BIOSes but no luck with any of them.Also tried with Fedora 25, 25 beta & Ubuntu 17.04 beta. Same behavior.ThanksStanoThanks for helping with this issue. I've sent a ticket to Asus, but I'm not expecting much. Then again, I felt the same way and Gigabyte actually sent me a fixed bios, so who knows.

I couldn't find Common Options at all, and here's a screenshot of the CBS settings:
gI suppose it wouldn't hurt to try to start the discussion with Asus. The video I found was this one:At that start time you can see an NBIO Common Options menu on an ASRock system, but I never saw him open it and I couldn't find any documentation on what might be in there in an asrock mb manual (not an endorsement for asrock, perhaps they just have a BIOS more similar to the AMD sample implementation). If AMD put it into a menu of debug options, it's really no surprise that consumer firmware dropped it. Too bad. This feels like a repeat of the difficulty we had trying to find motherboards that allowed the IOMMU to be enabled when AMD-Vi came out. I wonder if AVIC requires yet another BIOS option that consumers will need to gamble with.
