Hm, sounds like it. Micron is certainly reputable, and the issues hints at memory, although I’ve had similar that turned out not to be ram. Certainly very weird!

On another note, I personally do absolutely not trust btrfs due to its creator and very long time shaky lossy raid issues. Since there are enough performant and proven long time reliable filesystems available I use others.

Anyhow, getting to the point - I’d not entirely rule out something with btrfs as a separate issue too. I’ve just seen too many things that your ram issues could’ve been a few freak issues resulting in this.

Although I fully agree in your deduction!
