    Exclamation Getting Kernel Panic (MAY be related to wireless but not sure)


    Running Backtrack Linux R3 here, but this problem has been happening for a long time now.

    I get a kernel panic when I boot and no network connection is up, but If I plug an ethernet cable in the bootup process complets succesfully without error.

    This leads me to think that maybe the wireless is trying to do something that cause the computer to enter this state, but I am not sure.

    Since I am unable to gather logs about the issue (because the laptop completely locks up, only power button works) here are 2 screenshots showing the trace of the panic:

    Where can I start looking for solutions to stop this from happening?

    Thanks for all your help!!

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    What wireless device do you have, and what driver is installed?
    Ditto for the wired ethernet.
    Sometimes, real fast is almost as good as real time.

    You might check on the Intel web site for updated drivers. They are pretty good about keeping their linux drivers up-to-date.
