    SubjectPROBLEM: Kernel freezes when doing adsl communication
    Date
    1. One line summary of the problem:    

    Kernel freezes when doing ADSL communication

    2. Full description of the problem/report:

    While doing communication through my ADSL modem connected to
    ethernet, the kernel suddenly ejects error messages in
    /var/log/messages. I can usually go on working for another
    minute or so, and after that everything freezes or start to
    behave very strangely. It seems to be related only to some
    communication programs, e.g. gaim and mplayer seem to trigger
    the problem, whereas other, e.g. ssh, can work for hours without
    a problem.

    [3.] Keywords (i.e., modules, networking, kernel):

    networking, kernel

    [4.] Kernel version (from /proc/version):

    [6.] A small shell script or example program which triggers the
    problem (if possible)

    The problem is triggered by running certain communications programs
    like e.g. gaim or mplayer. Just doing ssh seem to be find...

    And as I said in the beginning, when this occurs the only thing I can
    do is to do a soft reboot. Any help is extremely appreciated!

    Thanks in advance!
