    2.2.18pre24 works just fine, sound and everything, with KDE 2.0. That's
    what I'm running right now. I had to fool around with the reiserfs-3.5.27
    patch for one file, but that was no problem.

    OK, I patched in the above for both 2.4.0-test12-pre4 and pre5, but did not
    get any "unable to enable" printk messages appearing in /var/log/messages.

    The behavior of course is the same, that is, sound will work under GNOME, but
    starting up KDE 2.0 freezes the machine. To get modules to work with
    2.4.0-test12-pre5, I had to modify linux/include/linux/module.h, line 348, as
    was the case with test12-pre4. This was the patch that was posted to the list
    by Mohammad A. Haque. (Put parenthesis around the bare some_struct).

    Here are some lines from messages for the three bootups which I tried:

    From 2.2.18pre24: (sound works with both KDE 2.0 and GNOME)

    I guess my next step is to learn how to set up a Serial Console for further
    troubleshooting. Any further help appreciated.
