[BUG] Intermittent Keyboard Lockup 2.6.25.5 with debugger under heavy loads

[Jeffrey Merkey]

Something changed between 2.6.35.1.  Under very heavy loads, I see the
keyboard loose interrupts and hang
when the scheduler is very busy.  Tracking it down.  Put a temp code
segment to read one of the keyboard
registers to clear previous pending interrupts.  The bug is the
keyboard gets a pending interrupt and never
services it.  Given the way the keyboard process is handled, looks
like a timing dependent scheduler bug
of some sort.
