Hi Liam,

I'll take a look at free, htop and Co, dmidecode, lshw, hwinfo,
/proc/meminfo and/or similar when I boot Alpine again. My Alpine is a
"System Disk Mode" install.

Are you using a "Diskless Mode" or "Data Disk Mode" install?
https://wiki.alpinelinux.org/wiki/Installation#Installation_Overview

With only 2 GiB of RAM a shared memory framebuffer might reduce the RAM
noticeable. I've seen missing RAM by hwinfo, with 4, 8 or 16 GiB RAM,
IIRC sometimes double the size of the framebuffer shown by the BIOS was
subtracted, but on my 32 GiB RAM machine hwinfo shows the whole RAM,
without subtracting the framebuffer.

Did you already run

  df -h

Maybe a strange tmpfs thing is shown?

Regards,
Ralf
