Sorry John,
Memory isn't as good as it used to be.  I went back and read the
entire conversation again and I think something clicked.  (Or maybe
just broke).  Try disabling viridian.  I just remembered when I loaded
Win8.1 just to test it out to see if it was bad as everyone said, I
ran into something similar.  If I remember correctly I completely
disabled viridian or at least until I had 8.1 up and running.
Like I said I'm not an expert on this.
Looking over your logs I don't see anything that stands out.
Hopefully something here helps.  If not hopefully one of the guru's
will step in.
Just out of curiosity, Is there is reason for disabling the IOMMU
remapping in your grub file?
