    Subject2.1.125 oops in ip_queue_xmit...
    I have "mystical" crashes with oops in the networking code.
    It's pretty reproducible (it just takes a time (between few days and few
    weeks) and a lot of network activity.
    Please contact me directly if you need any more traces.

    Below are:

    1. Output from ksymoops.c v0.6 (the standard ksymoops.cc didn't wanned
    to digest my hand-written oops trace ;):

    5. It's RedHat 5.0 based (means packages, were upgraded, changed or
    added :) with glibc-2.0.7-19 (RH).


    P.S. I've had similiar crashes with previous 2.1.x (x=105, 111, 115)
    kernels, but I don't have specific oops traces :(

    Thanks!
