Title:
  fwts: CMOS reading should have interrupts disabled during a read op

Status in “fwts” package in Ubuntu:
  Fix Released

Bug description:
  To stop any potential race conditions between writing to port 0x70 and
  reading from port 0x71 we should disable interrupts to be safe.  We
  can do this by:

  iopl(3);
  asm("cli");
  write to port 0x70
  read data from port 0x71
  asm("sti");
  iopl(0);
