Hi everybody
Environment here:
[root@caprioli ~]# cat /etc/fedora-release
Fedora release 32 (Thirty Two)
[root@caprioli ~]#
root@caprioli ~]# uname -r
5.6.10-300.fc32.x86_64
[root@caprioli ~]#
[root@caprioli ~]# grub2-editenv - list

suspend works fine on this machine, but hibernate does›nt. Another
installation on the same machine with fedora 31 hibernates/resumes
flawlessly.
I assume very much that when closing down for hibernate, no image is
created, because after booting up from (so to speak) hibernate, the last
lines in the journal are:
[root@caprioli ~]# journalctl -b -1
<snip>
May 10 09:47:53 caprioli.dyn.lan systemd[1]: Reached target Sleep.
May 10 09:47:53 caprioli.dyn.lan systemd[1]: Starting Hibernate...

May 10 09:47:53 caprioli.dyn.lan systemd-sleep[3134]: Suspending system...
lines 2285-2371/2371 (END)
where the 3rd line tells me, that no image has been created and written
to swap.
The swap partition has 19.6 GB. The memory is 16 GB. I tried to give the
system a much larger (1 TB) swap partition, no joy.
I also tried to go down to runlevel 3 before hibernating, and then
resume into runlevel 3: no joy.
I also tried to adapt the dracut command-line.
[root@caprioli ~]# dracut --print-cmdline
root=UUID=3f218a1e-7f30-48b1-add4-fb17bff5a6b5 rootfstype=ext4
rootflags=rw,relatime
[root@caprioli ~]#
to include the resume parameter, but dracut did not even take my
dracut.conf file into consideration.
Because the Fedora 31 installation on the same machine works flawlessly
as far as hibernate/resume is concerned, I assume the BIOS parameters
are such, that suspending/resuming is allowed.
Does the Fedora 32 Kernel, by default, prevent hibernate/resume?
I am at a loss of ideas on how to investigate further.
Any hint is highly appreciated. Thank you very much.
