Thats interesting. I have an old ThinkPad T42 above my hi-fi equipment as a 
media player and it stopped resuming from hibernation after some update quite 
some time ago.  But instead it just boots as if there would be no hibernation 
image. On hibernation it actually does write the hibernation image – I use in 
kernel hibernation, not userspace software suspend, but I think I tried using 
that one as well. Currently I don´t have uswsusp installed, but pm-utils is 
still there. I am not sure whether systemd uses it or does it all by itself 
tough. I configured in-kernel suspend there as well:

shambhala:/etc/pm> cat ./config.d/sleepmodule.conf
SLEEP_MODULE=kernel

Currently initramfs-tools is at 0.127 on this not so regularily updated 
laptop.


I never managed to get around actually looking whats going on here, but I now 
found that I do not have any resume setting in

shambhala:/etc/initramfs-tools> grep -ir "RESUME" .
shambhala:/etc/initramfs-tools#1>

Instead I have it here:

shambhala:/etc/default> grep -i resume grub
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda2 init=/bin/systemd"


shambhala:~> swapon -s
Dateiname                               Typ             Größe   Benutzt

shambhala:~> lsblk /dev/sda2

Okay, I will upgrade to the new initramfs-tools and look whether it fixes the 
issue. If not, I may try setting RESUME var to first "auto" and if not working 
still then the device in question to see whether that helps. I welcome any 
other ideas and I am willing to report back what I find.

Ciao,
