In fact it is even weirder:
'echo disk > /sys/power/state' -> it hibernates
First restart -> it resumes (displays the correct screen) and then halts
Second restart -> it resumes again and then FAIL.

I tried some other kernels from snapshot.debian.org

6.1.0-44        -> very good
6.5.0-0.deb12.4 -> good 
6.10.11+bpo     -> exit hibernation immediatly, does not halt (bad)
6.12.9+bpo      -> idem (bad)
6.12.43+deb12   -> idem (bad)
6.12.69+deb12   -> idem (bad)
6.12.74+deb12   -> idem (bad)

So actually 6.12.85 goes farther...

Cheers,
