Using NetBSD 7.0 amd64 it does not crash like this. It assigns IRQ53 for kbd slot.
The boot stops at this point:

boot device: <unkown>
root device:


Which is leading to the problem of the kernel (which all BSDs i tested have) not finding the root / boot device.

vendor 0x8086 product 0x0f35 (USB serial bus, xHCI, revision 0x0e) at pci0 dev 20 function 0 not configured

seems to have something to do with it. 

Should i create a new bug report for this?
