Hi, I've updated the BIOS on my Fatal1ty X470 Gaming K4 from 1.15A to 1.40 and I've run on some issues, which forced me to go back to 1.15A.

The problem has to do with virtualization and it seems that with the new bios the kvm_amd module on any kernel I've tried occurs some kernel errors.

My specs are:
- Ryzen 2700x
- 32GB - 3200
- Ubuntu 18.04

I've tried different kernels and I get the same issues. The error message when trying to load the kvm_amd module is:

Of course, amd-v and iommu are enabled in the BIOS.

I've noe reverted back to 1.15A and KVM works again fine.
