    Hi everyone,
    I've been using the eci driver for some time now, with complete success. It works very well. However, just recently, for no apparent reason, it appears to be losing connection. A NULL pointer in the kernel is causing the ADSL connection to die. I've attached the information from /var/log/messages. I hope someone can help!
    Thanks, Shane
