The problem occurs when you use certain SD cards, even if your system is installed on the eMMC and not on the SD card itself.
Apparently it affects cards that support "Power Off Notification" (see gitlab).
In my case a Sandisk Extreme 128 and a Sandisk Ultra 64 have the suspend problem whereas a Samsung Evo Plus 64 works fine.
