>60gb of reserved memory??

Dear all,


I just noticed a very weird problem on my workstation. Although the machine has 64 GB of RAM installed,

$ head -n 1 /proc/meminfo
MemTotal:        2400748 kB

that is, only a few gigabytes are actually available.

Unfortunately I don't have physical access to the machine, which is a HP desktop bought last fall. According to dmesg, the model is something like

[ 0.000000] DMI: HP HP EliteDesk 800 G3 TWR/8298, BIOS P01 Ver. 02.06 06/09/2017

Also according to dmesg, it appears that the kernel *does* see all 64 gigs, BUT OVER 60 GB IS RESERVED MEMORY!!

[ 0.000000] Memory: 2326720K/66985176K available (12300K kernel code, 1568K rwdata, 3836K rodata, 2124K init, 1368K bss, 64658456K reserved, 0K cma-reserved)

Does anyone have any idea of what could be going on?

I am running an up-to-date Fedora 27 x86_64 with kernel 4.16.15-200.fc27.x86_64.--
