As of 2.6.23-rc2, we should have: - probes for 8250 legacy devices (as in 2.6.21 and previous) - smsc PNP probes turned off by default (2.6.21 and previous had no PNP probes for smsc at all) - some complicated PNP quirks for SMCf010 devices In other words, I think we're basically back where we started. The 8250 driver should find a ttyS3 device at 0x2e8, and it should claim those ports, which will prevent smsc from claiming them. If you use "setserial /dev/ttyS3 none", the 8250 driver should release the ports at 0x2e8, and then the smsc-ircc2 driver should be able to load correctly. I think this is what we always had to do in the past, right? If that doesn't work, try removing the body of quirk_smc_enable() in drivers/pnp/quirks.c in addition. It's possible that the quirk changes the config in a way that messes up the smsc-ircc2 probe.
