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
