The plug and play option doesn't work for me (on a HP Compaq Business Notebook nx7000; kernel 2.6.24 and also the newer Ubuntu kernel 2.6.27).
Here are the relevant parts of the output of dmesg (if I load the module with the nopnp=0 option): serial8250: ttyS2 at I/O 0x3e8 (irq = 4) is a 16550A ... smsc_ircc_present: can't get sir_base of 0x3e8 smsc-ircc2 00:04: disabled Without any module-option smsc_ircc2 chooses IRQ 7 which conflicts with the parallel port (see bug 133169). If I instead load the module with the option ircc_irq=3, the relevant part of the output of dmesg is: Detected unconfigured Compaq x1000 family SMSC IrDA chip, pre-configuring device. Setting up Intel 82801 controller and SMSC device Detected Chip id: 0x5a, setting up registers... found SMC SuperIO Chip (devid=0x5a rev=00 base=0x002e): LPC47N227 smsc_superio_flat(): fir: 0x2f8, sir: 0x2e8, dma: 03, irq: 3, mode: 0x0e smsc_ircc_set_sir_speed(), Setting speed to: 9600 -- Consider configuring module smsc_ircc2 to use PnP https://bugs.launchpad.net/bugs/218661 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
