Hibernate in bookworm

Hi,
I just tried to hibernate a system which I upgraded from bullseye to bookworm
and it resumed and never reached the off state. I don't recall that there were
hibernation problems in bullseye on that system.
I tried out of KDE Plasma, but I also tried from the cmdline
root@h370:~# echo disk > /sys/power/state
-bash: echo: write error: Device or resource busy
root@h370:~#
Since
https://wiki.debian.org/Hibernation
looks somewhat outdated (describes Jessie and Lenny configurations), I followed
Arch and kernel documentation
https://wiki.archlinux.org/title/Power_management#Power_management
https://docs.kernel.org/admin-guide/pm/sleep-states.html?
highlight=image_size#basic-sysfs-interfaces-for-system-suspend-and-hibernation
Both
# systemctl hibernate
and
# echo disk > /sys/power/state
do not bring the system in hibernate mode (=suspend to disk).
The config I see on my system:
root@h370:~# swapon
NAME TYPE SIZE USED PRIO
/dev/dm-2 partition 15.9G 8.1G -2
/dev/zram0 partition 256M 256M 100
root@h370:~# cat /sys/power/resume
254:2
root@h370:~# lsblk /dev/dm-2
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
b370--vg-swap_1 254:2 0 15.9G 0 lvm [SWAP]
root@h370:~# cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-6.1.0-7-amd64 root=/dev/mapper/b370--vg-root ro quiet
root@h370:~# cat /sys/power/image_size
13375987712
root@h370:~#
Any hints are welcome
Thanks
Rainer

Try running a `sync` first to write all contents of RAM to disk.

I get an error, but this looks like the error is reported during the what
feels like a resume phase.

That does not change anything. Screen becomes black, but then it feels like it
is resuming immediately (without going through book, if feels more like a
resume as you would expect it from suspend-to-RAM.

Good luck.
