I have searched everywhere for an equivalent ( to su -; echo 1 > /sys/firmware/efi/secret-key/regen ) for kernel 6.15 and I am stumped.
I t seems the issue is that the above relates to the
patch that allows generating and storing as UEFI variable a secret key used to encrypt hibernation image
(quoting from topic 184133) [in 15.6 stock aka 6.4] being missing in the 6.15 backport kernel. So my options seem to be:
- Revert to 15.6 Stock (6.4) kernel, breaking sound, dock support etc. on this laptop but regaining hibernation.
- Keep 6.15 and live without hibernation but enjoying the many other fixes
- Build my own kernel with the patch, though I assume I somehow have to sign it & enrol the signature in MOK before it will work with secure boot? And is the patch likely to be usable with 6.15? Maybe it’s not present for a good reason…
Thanks in advance
