Others on the forums suggested (in 2003) that I should disable PNP feature in BIOS, which is impossible for me because my old IBM Thinkpad don't offer such config option (the only config option had been change system date/time and start-up-sequence). Even if it doesn't affect the use of the system I'd like to know a bit about the background knowledge. At least two devices on my FreeBSD doesn't work, the COM port and the second PCMCIA slot (anything on that slot doesn't work), though I don't think the two devices are related to this kernel message.
