Really depends how paranoid you are: https://en.wikipedia.org/wiki/Cold_boot_attack If you want to be as secure as possible you should consider anything in memory when suspended potentially accessible. This includes disk encryption keys as well as other keys you may have loaded (e.g. keys that are fully resident in ssh-agent). Linux has a "luksSuspend" feature, although that recently had a bug where it turned out it didn't delete the keys from memory as it claimed to[1]. OpenBSD doesn't have such a thing.
