Dot, RE: Modem interrupt assignment and sharing: 11: 7481 XT-PIC-XT ehci_hcd:usb1, uhci_hcd:usb3, ohci1394, yenta, eth1, yenta, Intel 82801DB-ICH4, eth0 --- The problem is probably to many devices sharing IRQ 11 with the modem having the lowest priority. Detach as much external hardware as you can before reboot. Afterwards: $ sudo ifconfig eth0 down $ sudo ifconfig eth1 down Unload and reload the driver: $ sudo modprobe -r snd-intel8x0m $ sudo modprobe snd-intel8x0m and rerun: $ ./scanModem Hopefully there will not again be: [ 456.755680] Intel ICH Modem 0000:00:1f.6: PCI INT B disabled [ 456.755699] Intel ICH Modem: probe of 0000:00:1f.6 failed with error -13 which must be cured before the modem can be responsive.
