Nope, it was completely clean and so was the cardbus socket (the wifi<br>
card works in both cardbus sockets). Three hours of google searching<br>
led me to blacklist the smsc_ircc2 module which woke up the serial ports<br>
(both the on-board and the modem) and everything started working.<br>
Somehow that module (used by the IrDA module) causes issues with serial<br>
ports on many laptops. I don't know why, that's probably more google<br>
searching. I don't need IrDA support (though it would be fun to play<br>
with since I have several IrDA enabled devices) but it would be nice to<br>
find out why smsc_ircc2 messes things up.<br>
