--- Comment #7 from Georg Schukat <georg.schukat@xxxxxxx> ---
I further investigated the problem I had seen.
Doing so it became clear that the problem is not a kernel issue.
The partial amount of memory seen by the kernel depends on BIOS/Legacy boots.

If any Linux (Ubuntu, Leap 42.3, Tumbleweed) is EFI booted the reported
physical memory amount is correct. Only if the same OS/kernel is booted in
Legacy/BIOS mode, /proc/meminfo reports the reduced amount of main memory.

Same reduced memory in kdump-yast2, see screenshot.


My conclusion is, the root cause must be something else, probably a BIOS issue?


From my point of view, the reported problem is resolved.


There are other problems with Leap 42.3 on my laptop.

1. iGPU seems to be still unsupported
2. iwlwifi is missing the right firmware.

I will open new bugzilla reports for both and attach the same dmesg etc
diagnostics.
