The right way to find the culprit is to unwind the stack by hand to find who called outb. Seems removing the offending driver from the .config should solve the problem for now. The right fix is to modify the driver so it doesn't poke IO port space unless it's clear the device lives under a suppported bus. > I also refresh the files on th server.
