Hugo Just been doing some testing, without AGRmodem hardware on my system The modules compile under Ubuntu 2.6.22-14-generic But after the $ sudo depmod -a and upon attempted $ sudo modprobe agrmodem There is agrmodem: Unknown symbol agr_pci_get_irq I presume this doesn't appear on your System with the modem hardware present. If this is the case, the agr_pci_get_irq must in some way be acquired from the firmware on the modem card. MarvS
