General Questions • [Software] Hibernation with encrypted swap and secure boot

I am using Debian bookworm and I have secure boot enabled with full disk encryption. My swap partition is also encrypted (confirmed by `fwupdmgr security --force`). However, the kernel lockdown is still preventing me to hibernate.

In dmesg I see:

Code:

[    1.584258] Lockdown: swapper/0: hibernation is restricted; see man kernel_lockdown.7
But in the kernel_lockdown.7 manual it says:
Unencrypted hibernation/suspend to swap are disallowed as the kernel image is saved to a medium that can then be accessed.
So if you have your swap encrypted, it should *not* prevent hibernation. So what is going on here? Anybody knows?
