  /proc/meminfo reports 6.7 GiB, while lshw reports 8 GiB, meminfo
  reports 1.3 GiB less than lshw, a difference of 16.27%

Status in linux package in Ubuntu:

Bug description:
  I have this laptop Acer Aspire E5-551G-T0KC http://www.acer.de/ac/de/DE/content/model/NX.MLEEG.009
  It has 8 GiB memory.

  Meminfo system test fails with this message:

  "/proc/meminfo reports: 7024084.0 kB lshw reports: 8388608.0 kB FAIL:
  Meminfo reports 1397272576 bytes less than lshw, a difference of
  16.27%. Only a variance of 10% in reported memory is allowed."

  I didn't test any other kernel because I don't know which version I
  should install.

  The system testing report is attached.
