OK, I had these already in my kernel, and it still doesn't work.
I already tested out almost every combination possible within Fiasco, incl. PIC,

I have attached a serial cable and logged what the kernel debugger says. There is an
unhandled pagefault. Below you'll find some output of the log.

Best regards,
