Hi
Afterwards I noticed that after I managed to boot 6.9.0, it hibernates
and even wakes up OK, so it can read the hibernation image. The panic is
there only when the system is coming up after rebooted. Then I need to
edit out resume= and resume_offset= from grub to not get the kernel
panic. (grub with non-UEFI legacy boot.)
