After a little digging I found the likely culprit, it's a known issue with AMD AGESA and the Linux kernel compile option 'CONFIG_CRYPTO_DEV_SP_PSP: https://bugzilla.redhat.com/show_bug.cgi?id=1608242 https://bugs.archlinux.org/task/59483 http://forum.asrock.com/forum_posts.asp?TID=9179&title=new-asrock-x470-taichi-uefi-150 Quote from the RedHat Bugzilla:
Good news, I have received a reply from AMD regarding the issue after submitting further information as gathered above and from other sources.
Quote: It would appear that the BIOS/firmware is advertising it supports SEV, when in fact it doesn't. We currently don't have a timeout associated with the SEV commands and so the module load is stuck - which would also explain the KVM issue.
The current approach is to add a timeout to the kernel that stops things sticking forever and submit that to the current stable releases.
A fix is also underway, but it will take a while to reach Tumbleweed or the Leap stable kernel probably: https://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6.git/ commit/?id=3702a0585e64d70d5bf73bf3e943b8d6005b72c1 regards
