You use the slamr module instead, with your pci modem. I'm observing a problem with the usb, where the modem seems to lock up and gives the message "fifo underrun" in the /var/log/kern.log. This happens every hour or few. The only way to recover is to stop dialup, rmmod the module (slusb), then modprobe and restart the driver and dialup. I have previously reported this here, and believe it's being worked on. Are you having this same problem with the slamr in kernel 2.6.20? Have you run it successfully for several hours? regards,
