more random thought: I've had issues with bad RAM two times in my life. it takes me some time to get from "huh, my browser segfaults pretty often, that seems weird" to "maybe I have bad RAM?". if Linux had support for scanning for bad RAM on segfault, that'd be cool

you'd probably want to apply some ratelimiting - if a bunch of crashes happen and the first few aren't due to bad RAM, it's probably not very useful to keep scanning. and you could perhaps make sure that if the system is under memory pressure, unscanned memory is given back

Having worked for a while on memtest86 I can assure you that testing if modern RAM is bad is difficult. The easy cases rarely make it out of the factory. What you are left with are difficult cases like burst transfer errors. Using ECC is a much easier solution.
