Somehow, restore from hibernation, aka suspend to disk, is not working. It silently boots instead, after I enter the decryption password on Grub prompt.
Next step will be attempting it, and examine journal on next boot. I have not tried for a few days, so the log entry pertaining to the failure I don't know where it is.

I see this in the log of the next boot just when I hoped it would restore from hibernation:

It is already too late. Add printk.devkmsg=on to kernel parameters and provide dmesh output after resume.
The kernel boot line at the start of the journal is:
