this has been evident to me for quite a while, just haven't had time to
deal with it. It's particularily frustrating since this is a clear case
of defective hardware.
the solution:
if ( TIMER_IRQ_IN_MPTABLE ) {
setupAPICTimerIRQ();
spin( aWhile );
if ( intcount > 0 ) return 1;
}
setupMixedModeTimerIRQ()
spin( aWhile );
if ( intcount > 0 ) return 1;
panic( "this eats it!!!" );
