Those are good data points!
They indicate a coreboot problem; ie. not at all related to xen/Qubes.
Now it would be very helpful to get debug output from coreboot, which
requires specific hardware. With luck you can use a USB->serial-adapter
that you already have (only specific ones work), otherwise you'll need
e.g. a BeagleBone Black to function as a USB Debug Device.
Or if you are really lucky :) the KGPE-D16 already has a serial port
and you just have to rebuild coreboot with debugging enabled.
