I had a laptop that got a huge performance hit from the kernel fix that "fixed" spectre. It rendered the laptop garbage. I was thinking to reuse that laptop simply for music / news / surfing as a work alternative laptop. I looked into if it was possible to turn off the spectre fixes and if it was possible to check if the fixes were in (or they came up with a faster fix). Found that you can check if it's being "fixed" with lscpu. And a grub flag can tell the kernel to turn them off.

better than if it died all together. The first time I had an SSD die, I had no idea it blanks the entire boot process. I tore the entire fucking thing apart trying every other piece ( including the CPU itself) before figuring out the SSD was the cause. Old HDDs would at least boot and tell you they're dead. SSDs die and take everything with them. M2's probably do the same
