Right, the first one is from 8250.c. The second one is certainly weird, the 8250_pci driver should have been able to register the ports it found. > I tried to contact a simple external modem using the serial port but > it didn't work so i am afraid something went wrong with the driver... When the serial port can't be registered, contacting anything connected to it will fail. Something wrong with the driver indeed. FWIW: my machine uses 8250_pnp and that works OK. You might want to compare the setup code in the drivers. Erik -- They're all fools. Don't worry. Darwin may be slow, but he'll eventually get them. -- Matthew Lammers in alt.sysadmin.recovery
