> lots of people encounter problems with sleep on linux

Yeah, because they buy a Windows laptop, slap Linux on it, and expect it to work.

OSX sucks even more by this metric; it won't even install!

I was looking into hibernation on my Framework 13 with Ubuntu. Debian doesn't support it with SecureBoot enabled. Now you might say "just disable SecureBoot", but that is a whole new concept to understand.

I've found suspend performance has improved since upgrading to a kernel that supports the AMD 7640U NPU cores. I have no concrete evidence of that though.

I'm happy to accept poorer sleep performance to have a repairable laptop and Linux OSS (with good support), but I wouldn't say its problem free.

Well if you buy a Linux laptop and slap Windows on it, sleep will most likely work. Unfortunately Microsoft got preferential treatment.
