Please resend on top of latest v6.6-RT. Lazy preempt is gone so only
PREEMPT_RT config switch remains from your three patch series. If you
have generic-entry then you could use the new PREEMPT_AUTO.

Are there any reports of this booting without warnings with LOCKDEP and
CONFIG_DEBUG_ATOMIC_SLEEP enabled? I remember there was something
earlier.
