   I think we are getting somewhere, there is a mce on the number of CPUs:

   I've tried setting "amd_iommu=on" in default/grub. I'll try iommu=soft and 
report back. Is there anything else to check? Funny, my IOMMU doesn't seem to 
trigger any issue:

<snip boot continues normally>

I'll keep digging, but this is got me stumped.
