How to blacklist particular defective RAM areas on a machine with Linux?
Well, the first and main reason which you probably guessed is because recently my laptop turned out to have a defective RAM and I had to do something with it as it became unstable to work on. The second reason is because I didn't even know that there is another way than just replacing the RAM (for the record if you can just simply replace the RAM stick then I don't recommend using a PC with a faulty RAM; however in my case the laptop has a soldered-in RAM which makes replacing the RAM impossible for me and pretty expensive in a repair shop). The third reason is the fact that even tho I learned from a friend what I should use to "fix" my issue I couldn't really find any reliable info how to do it now because in 2023 no one does it anymore (it was vastly more popular 20 years ago when RAM was expensive).
