boot -s hangs just like normal boot unless I unplug the mouse.  After 
boot -s with ums unplugged, I can fsck if necessary and then mount-a, 
installworld, etc. with no problems.  I can even plug in the mouse, not 
that it helps because I still have to unplug it when I repoot after 
mergemaster.

I have never experienced a panic or other crash related to USB devices. 
  Only the boot lockup.
