Yes, that was the issue! What I did to fix it (DISCLAIMER: I tried various things until it worked, not all steps might be necessary):
- Edit
/etc/kernel/cmdline
, removeresume=UUID=...
argument. - Run
dracut --kver 6.8.10-300.fc40.x86_64 --force
as root. - Edit
/etc/default/grub
, removeresume=UUID=...
argument. - Run
grub2-mkconfig -o /boot/grub2/grub.cfg
as root.
