    I am having the same problem with my Shuttle FT61 motherboard, although
    I have not tried to disable ACPI... Until now I thought I just had a
    faulty keyboard, as my method to fix this was to unplug the keyboard and
    plug it back in after bootup. When this happens, I see this in dmesg as
    the last line:

    input: AT Translated Set 2 keyboard on isa0060/serio0

    I am also having problems with my AUX mouse, as seen in message

    Subject: 2.6.12-rc5-mm1 breaks serio: i8042 AUX port

    Frank, are you having problems with your ps/2 mouse port as well?

    I haven't spent enough time experimenting with this, as I thought it
    might have had something to to with my hardware / KVM switch. Seeing
    Frank's message is the reason why I've decided to chime back in on this.

    As a clarification, I have been having these keyboard problems
    intermittently, regardless of whether I'm using -mm or mainline kernel.
    I was NOT having this problem in 2.6.11 I wasn't having the psaux mouse
    problems in 2.6.11 either .... I unplugged my psaux mouse from that
    machine before 2.6.12-mainline was released, so I don't know if those
    symptoms are still present. (using USB mouse now instead). I am
    currently in my office, so I can't test this right now, and I will be
    away for this weekend. I'll be able to make these tests again come
    Sunday night/Monday. ...and I will try it this time WITHOUT the kvm
    switch.
