Looks like you were right (nice catch)! If I boot my laptop with my
logitech USB mouse (ums0: Logitech USB-PS/2 Optical Mouse, rev 2.00/11.10,
addr 2, iclass 3/1 ums0: 3 buttons and Z dir.) it seems to crash with or
without AC power hooked up. But I know for sure it's crashed with no
mouse hooked up. And I also know for sure that it doesn't crash if I have
the mouse *and* a USB keyboard hooked up.
Thanks again for the suggestion...anything I can do to fix this?
Thanks,
Mike
