I see lots of “IN from bad port” errors in my kernel dmesg, how do I fix that?
This is caused by drivers written for devices that you don’t have on your system. These messages are usually harmless, but it’s a good idea to disable the unused drivers anyway. See below to match up port numbers with kernel configuration options. Note that even if the numbers don’t match, try disabling these kernel options anyway, most PPC machines don’t use these drivers.
