When removing PS2 devices this tends to cause the PS2 buffers to fill up
and get dumped. the kernel turned offunused PS2 connected items (mouse for
instance() and should it be removed and placed back on to that box
movement will eventually fill its buffer and hang the just the
console. Thi can be demonstrated by eitherunplugging and plugging the
mouse or thru the use of a KVM Switch like a belkin omniport
