Linux Mint 21.1 sometimes suspend-to-ram works, sometimes it freezes
I've been having intermittent trouble with suspend-to-RAM on Linux Mint 21.1 on x86_64 with the 5.15.0-58-generic kernel. Most of the time it suspends and wakes just fine. Other times it freezes, either when trying to suspend or when trying to wake. I'm not finding any information in the logs. How or where should I be looking for a solution so that it suspends successfully and resumes successfully each time?
Below are some log excerpts from the time frame of the latest freeze.

Reason: suspend-to-ram
You don't have enough swap for hibernation. It's more like on the edge (You need some extra swap for programs that use it). Try making your swap 24GB and see if the problem persists.
I just found out you are doing suspend-to-ram, can you edit the title so it says suspend-to-ram?
You possibly configured it wrong, and it is using normal hibernation-to-swap

Thanks. I had suspected that. It looks like I'll have to set aside time to redo the partitioning on that system. Unfortunately that probably means a clean installation of a fairly complex setup. The Linux Mint installer uses only MB if I recall correctly, so it may take a few tries or is the 24GB not a precise requirement and only an approximation?

It's the default setup but it does seem like it's doing hibernation rather than sleep.
