      For am62p RT kernel boot, randomly 'Unable to handle kernel NULL pointer dereference' kernel oops can be seen randomly on cicd.scarthgap.202509220638 tag.

      Issue seems to be related to incorrect/race with PM domain referencing.

      Temporary solution is to disable simple frame buffer for RT, but we loose flicker-free splash transition with RT build.

      It is also worth noting that the issue may not really be specific to RT-LInux it's just getting exposed due to aggressive preemption. So there is a risk of seeing this race condition with non-RT as well.
