[solved] Resume from hibernation silently fails (Lenovo T14 gen5)

Hello,

I have a clean arch install on new laptop (T14 Gen5 AMD)
I tried to setup hibernation but there is a strange issue - from the logs everything looks ok, but after resuming the system is in clean state like it was started without stored info.

I have luks encrypted btrfs, swapfile is on submodule in /swap
If I understand the wiki correctly no further settings like kernel params or mkinitcpio hooks should be needed.

$ swapon
NAME           TYPE      SIZE USED PRIO
/dev/zram0     partition   4G   0B  100
/swap/swapfile file       32G   0B   -2
