Under heavy load, MX5 systems can exhibit the following error:

        "Invalid Page Table Entry on Scatter Gather access"

or an undetected data corruption.

The recognizable symptom for this problem is an uncorrectable machine check
where the crash-data file register dump will have the following lines:

  CIA/PYXIS ERR                 = ffffffff10000200
      Invalid Page Table Entry on Scatter Gather access
