Huh. So when hybrid suspend+hibernate happened, I had a randomly encrypted swap setup. So this obviously can't ever be recovered from, because the key is lost. Well, actually the key is in the image on encrypted swap. So the only copy of the key is encrypted. Ha. Anyway, after setting up an ordinary plain partition swap, updating fstab, and adding resume=UUID= boot param; plain hibernate with 'sudo systemctl hibernate' enters and exits hibernation normally even though Secure Boot is enabled. So something has changed. I've asked on the kernel list. I haven't tested hybrid sleep again yet, so I'm still not sure what that immediate wake up is all about. Anyone looking to get more info about this should add the 'no_console_suspend' boot param. It might help give an idea what's going on, but there's also some chance this ends up relating to ACPI (a very deep dark rabbit hole). --- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx/message/4VVRN6B3GODX35RUG6DDLJIQNVDICCUH/
