I have a laptop with 16G of RAM, but NixOS often only detects about 2.5G of it. The problem often goes away after a reboot, but last time it took about 10 reboots to get my memory back, and that’s pretty annoying.
Also, the ‘reboot’ command doesn’t work for me, although I don’t know if that’s related.
Thanks in advance
PS: This is the current Output of the ‘free’ command:
total used free shared buff/cache available
Mem: 2593576 1989576 229740 20660 374260 290316

I’ve ducked around a bit, it seems most other people reporting similar things had physically mis-seated sticks, BIOS issues, the occasional UEFI vs legacy BIOS, or just broken motherboards. It seems to be failure before Linux boots more often than not, and that seems consistent with the flaky behavior.
Why it shows up as “reserved” is probably a question for the kernel ML rather than here.
If this is a laptop you didn’t modify yourself, I’d give updating the BIOS a shot, and make sure I’m booting via UEFI (frankly the latter is unlikely to be the issue in 2023). If that doesn’t fix it, I’d start digging around with dmidecode and memtest.
Thanks for the response, I’ll have a look at updating the firmware as I’ve not done that in a while.
Probably not, what happens when you use it?
Nothing. When I do reboot now it complains about missing permissions, when I do sudo reboot now it prompts me for my password, exits without any output or error, but does not shut down or reboot my Computer.
Hey, sry for the Delay. I’m not that familiar with those logs, so not everything I pasted below may have something todo with my Problem. Thanks again for helping
