I updated my 4.6 box to 4.8. In 4.8 there's a problem using fast
interrupts for some reason. This is a dead simple 486 box, without
pci or pccard. I've included the entire dmesg, since it is so short.
Looking at the code, it fails because it fails. No clue why it might
be failing. Since this is my main firewall box, I'd like to get it
using fast interrupts again to make the console working.
