You’d think journactl would be the right thing here to diagnose it, but it doesn’t seem to find any sigkill or sigterm. I used journalctl a lot to diagnose a slow shutdown, that ended up working much much later once i figured it out with a lot of help from here.
What worked for you? It takes about 1 minute for it to go from click suspend to go fully suspended. Anyone familiar?
Is it really “suspend” AKA “suspend to RAM” or “hybrid suspend” where a compressed image of memory is actually saved on disk (usually on a swap partition)?
If the latter, if you have a lot of memory data and the disk is relatively slow, taking up to a minute might not be uncommon.
