RH9 boot crashes and loops - Linux Setup, Configuration & Administration

I'm trying to boot Red Hat 9 on an eMachine. I can boot from the CD fine and have it all installed, but when it boots the "real" kernel from either HD or floppy, it looks like it's crashing right after the kernel is decompressed, and then goes into a loop printing what appear to be various entry points. This goes by too fast to read the initial error message (the register dump is the first thing I can see clearly) and the system ignores the keyboard, so I can't pause the display. What can I do to debug this? ...

    Default RH9 boot crashes and loops

    I'm trying to boot Red Hat 9 on an eMachine. I can boot from the CD fine
    and have it all installed, but when it boots the "real" kernel from either
    HD or floppy, it looks like it's crashing right after the kernel is
    decompressed, and then goes into a loop printing what appear to be various
    entry points. This goes by too fast to read the initial error message (the
    register dump is the first thing I can see clearly) and the system ignores
    the keyboard, so I can't pause the display. What can I do to debug this?

    The keyboard is USB. Would that be an issue? Right after the register dump
    (the part with the EIP display) the first entry point looks like
    n_tty_receive_buf, but that rapidly scrolls off the screen and I see
    various symbols that appear to be part of the network stack, with ip and
    tcp in the name.

    Aha, the chroot makes it possible to install RPM's into the system-under-
    test.

    I've manually edited grub.conf before on other systems, so I'm pretty
    comfortable with getting that working. (Well, as comfortable as one can get
    editing a critical boot file. ;) At least the rescue CD lets me fix any
    boo-boos.)
