I was finally able to take a picture of the crash without PS/2 ports disabled 
in the kernel and compared it to dmesg output with the ports disables

I see this in my working dmesg

And this with the PS/2 ports enabled - typed by hand, hopefully without error.

As you can see, there is no mainbus0: scanning line - why should this be?
Hopefully this helps someone fix this.
