Hi, I have one additional information, when following the "Kernel testing facility" description in
https://wiki.debian.org/Suspend freezer test the freezing of processes devices test the freezing of processes and suspending of devices platform test the freezing of processes, suspending of devices and platform global control methods(*) processors test the freezing of processes, suspending of devices, platform global control methods and the disabling of nonboot CPUs core test the freezing of processes, suspending of devices, platform global control methods, the disabling of nonboot CPUs and suspending of platform/system devices On my system # echo freezer > /sys/power/pm_test # dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after resumes successfully. # echo devices > /sys/power/pm_test # dmesg > dmesg_before; echo mem > /sys/power/state; dmesg > dmesg_after does not resume anymore and shows the issue described before. Or to be precise: the screen shows a blinking cursor, when it reaches the hang situation during suspend. This is different than what I would have expected, it seems that not only powering off does not work (then I would have expected an issue in the last step of the sequence described above. Here I am stuck now, please let me know if there is more information I can provide.
