    I have been experimenting with USB legacy and with PS2 versus USB and
    the result is:

    1. PS2 keyboard in combination with SMP gives the same result, it just
    takes longer to happen.
    2. disabling USB legacy results in the BIOS not recognizing any
    keyboard. It does recognize the mouse even though both keyboard and
    mouse are wireless and thus connected through the same USB device.
    3. Only the UP-kernel is trouble free (as far as USB/PS2 keyboard is
    concerned).

    I have also found a bug that describes my problem (more or less) so I
    added comments to it:

      Bug 154539 processed: Kernel 2.6.11-1.14 & 2.6.11-1.27 break USB
      mouse/keyboard.

    Guus.
