The joke is, the >60GB of missing memory doesn't even show up in free:

$ free
total used free shared buff/cache available
Mem:        2400708     1093732      284844      121920     1022132 957848
Swap:      62499836           0    62499836

For some reason the kernel marks it as reserved.

Same goes for htop. It's showing I have 2.29G of memory.


Update: I upgraded from Fedora 27 to Fedora 28, and the same issue persists. Of course, the kernel is almost the same.

This has to be some weird kernel / BIOS bug...
