    Well there are 2 things that you have at your disposal depending on what you need to do.

    1) If you can upgrade to Fedora 7, do that. Hardware issues are generally kernel related, and going 3 revs is definitely changing your kernel. Also, if its not the kernel, a new version of ALSA may help too.

    2) Drop to single user and manually update your system. Mind you, FC4 is ancient, and no longer supported. I am not sure what a 'yum update' will do for you.

    If you are being told that you need FC4 due to a class or something, update anyway or reinstall FC4 in a vm (like vmware of virtualbox) on your Windows or Mac based machine. Linux has been perfectly supported on vms for ages.

    Of course you have sorted the problem out since July, but I wanted to say that it sounds like a problem of IRQ allocation frequent on older pc most often occuring with sound cards which by default will use an interrupt which conflicts with another device.
    It used to be the IRQ 5 and sometimes the same IRQ 11 as the modem, resulting in the modem not connecting to the Internet.

    In your case, not booting since the sound card is enabled, then it's because the sound card is using (by default, by manufacturer settings) an IRQ belonging to another device, one essential to system initialization.

    Actually the system stops while initializing the hardware, telling you that there is a problem: conflict of hardware allocation sharing.

    anyway, I just wanted to say this, as I don't think tha tin this particular case upgrading to a later system would change anything.
    removing the card would cure the problem.

    $ cat /proc/interrupts

    see also:
    cat /proc/dma and /proc/ioports

    so to install a sound card
    $ sndconfig [options] sndconfig is a txt-based tool used to conf the sound card.
    sndconfig --help
    sndconfig --noprobe
    sndconfig --noautoconfig
    making sure that there are no conflicting devices, since sndconfig won't detect the problem.
