    Since the volume is high on this mailing list while the signal-to-noise is
    often low, I would appreciate any communications on this to be done off-list
    (I will post any results to the list).

    I have a Compaq R3000z (Athlon64) notebook. There are multiple systems
    installed: WinXP on a shrunk hda1, swap on hda2, a FC3 minimal install on
    hda3 as a boot director, FC3 i386 everything install on hda5 and FC3 x86_64
    everything install on hda6. My problem(s) occur identically (as far as I can
    tell) on both the i386 and x86_64 systems.

    Booting with ACPI=ON (actually specifying nothing at boot time):

    1. The integral synaptic touchpad is detected as a generic PS2 two-button
    input device.
    2. A USB (1.1) mouse is not detected/useable.
    3. USB 1.1 flash drive is not detected although USB 2.0 flash drives are
    detected and useable.

    Booting with ACPI=OFF:

    1. The integral synaptic touchpad is not detected.
    2. The USB (1.1) mouse is detected an useable. It can be hotplugged if not
    present at boot time.
    3. Both the USB 1.1 and the USB 2.0 flash drives are detected and useable.

    Bug reports have been filed:
    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143893
    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143894
    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143895

    There are some bug reports filed at bugzilla.redhat.com which may be the same
    thing or at least related. However, nothing recent which sounds like this.

    I also searched bugzilla.kernel.org and came up with some reports indicating
    problems in the 2.5/2.6 kernel with USB/ACPI (one very old report pointed me
    in the right direction).

    I have also tried these devices on a ASUS SK8V/Opteron system and everything
    worked fine there. This "problem" seems to have been around for a while and
    I know that there are Compaq R3000z notebooks (or the HP equivalent) out
    there being used with FC3. I am a bit surprised that this problem is not
    more widely known.

    I am also interested in trying a "generic" kernel from kernel.org if that is
    possible/practical. Does anyone know if it is "safe" to run the generic
    kernel without all the Red Hat/Fedora Core patches (a lot fewer patches than
    SUSE run but nevertheless a significant number).

    Any help will be appreciated.
