Here is some more data to add to the HCL. Qubes works out of the box, except the IOMMU due to a chipset errata. It looks like there is some work arounds for getting the IOMMU to function without "Interrupt Remapping" which is significant.

I also have a Z800. I've been trying to install 4.0-rc4. The installer tells me that the following features are missing:

IOMMU/VT-d/AMD-Vi
Interrupt Remapping

I have a ticket open on the HP support forum asking for help. Someone helpfully suggested a few BIOS settings that I might try, but I have not been having any luck.

Might anyone here have any suggestions?

One other clue: Someone on the HP support forum suggested that the problem might be related to the x58 chipset and sent me a link to a data sheet:

https://www.novell.com/support/kb/doc.php?id=7014344

I'll be reading that data sheet more closely later today, but my current impression is that solving the problem would take a BIOS patch. Or maybe the chip firmware can be flashed directly? But even if it could, the underlying instability might remain. I just don't know.
