    Kernel oops in maestro3/sound on Dell Inspiron 8000

    Hi guys!

    I have been trying to get sound working on my Dell Inspiron 8000 lapop.

    Under Knoppix 3.6, it works fine with kernel 2.4, but under kernel 2.6 it
    crashes with a kernel "oops".

    Under Knoppix 3.8, it also crashes, but i don't have the option to use
    a 2.4 kernel

    The laptop boots fine, but I do not get the voice "initiating starting sequence"
    with the 2.6-based Knopix. The process generating the audio hangs, and
    any attempts to use audio afterwards crash, and cannot be kill -9'ed.

    Has anyone got the maestro3 working in this configuration before?
    How can I fix it so that sound works with Knoppix 3.8 and beyond?

    The problem appears the begin during boot, where the following
    messages are output:

    (after a *lot* of messing around...)

    There seem to be two sets of maestro3 kernel modules - the one at
    and the one at

    The first one of these hangs when you try to play sound. This is the
    module which gets used by default.

    If you use the "alsa" cheatcode when booting, it doesn't load this module.

    Then from a root command line type:
    modprobe snd_maestro3
    and it will load the ALSA modules instead. These work, but are
    initialized to volume=0, and are silent initially.

    I tried "alsa=maestro3" cheatcode, but this doesn't load the module

    What is the correct cheatcode to use the alsa module?
