Kernel 6.4.3 comes with lockdown enabled

JFYI: Kernel 6.4.3-3.g5ab030f-default from Kernel:stable has lockdown enabled (i.e. "cat /sys/kernel/security/lockdown -> integrity"), which was announced some time ago. Since hibernation is not working in this case with secure boot enabled, is there any solution in sight? Thx. Regards, Frank
