[Bug 880472] Re: fwts: CMOS reading should have interrupts disabled during a read op

[Colin King]

@Martin, I'm not sure how we proceed here, since we'd like the new
version of fwts 0.24.14 to be uploaded and hence superceed the older
version fwts 0.23.25.  The newer version will include this bug fix as
well as a bunch of other fixes and new features for Precise.

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

Status in “fwts” package in Ubuntu:
  Fix Committed

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);
