I just wanted to create an issue for the problem I mentioned in chat.
It worked for me that my GNUK token survived "systemctl suspend". I could just use it afterwards.
With my OpenPGP 2.1 card in the SPR-532 that never worked. There was always the error "Card reset required".
Now my "Bug" report is: When "card reset required" shows up as an error. I can kill scdaemon and then it works again. So if I can fix it by killing scdaemon it should be possible that we can fix this state by itself. For me it seems like a software error which we can solve.
This might be a systematic problem so I am very fine if you put it on low priority. Personally it does not have high priority for me. I'm used to it. I just wanted to document it.
If you cannot reproduce this issue (as I partly understood from your chat) I can of course create logs.
