RIP S3 sleep... Took years to get it to work reliably under Linux, then we had a good decade+ run of it "just working" like this, now back to trying to weed out all the wacky platform quirks and weird hardware/firmware behavior that make the S0ix states be just barely unusable.

Maybe in another five years...

Can you explain a bit more? What happened?

Linux used to be able to do S3 sleep well, and now it can't because... new platforms removed S3 for S0ix? Or S3 became even more complicated with mroe platform quirks and weird hardware?

The problem is platforms moved away from S3 sleep. I've heard people claim it was mostly so managed Windows laptops could force updates with the lid shut and the laptop suspended.

Now I have to worry about my laptop randomly overheating itself in my backpack and even catching fire.
