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.
