  Modified files:
    sys/i386/isa         clock.c 
  Log:
  Anytime we write to the RTC's status B register to possibly enable
  interrupts, read from the interrupt status register to clear any pending
  interrupts.  Otherwise in some rare cases the RTC would never fire any
  interrupts as it constantly thinks it has an interrupt pending.
