Comment 12 for bug 1471119

That is very, very strange. I can't see how any of these could possibly make a difference, but I did notice that your working boot uses these three command line arguments:

pcie_aspm=force nomdmonddf nomdmonisw

You might try pressing F6 when booting the installer and add those arguments to the kernel command line ( before the -- ), and see if it changes things.
