Since we have no idea of your mainboard chipset, it might be hard to get
knowledgeable people to spend their time on it. I'm not knowledgeable,
but have a general background.

Based on the messages, I would check the BIOS setup, as the messages
suggest. It may be that the 4.x stuff driver(s) didn't depend on an IRQ
while the 5.x might. Just a guess. I guess a conflict is also possible.

If you don't see anything to change and test, I suggest you post back
with more info so experienced folks can help.
