This seems to be a false-positive because the two stacktraces are identical but pciehp_ist() is single-threaded. There is only ever a single instance of pciehp_ist() running per hotplug port, so two instances running on separate CPUs can never happen. Previous reports of the same false-positive lockdep splat, only they refer to pciehp_configure_device() instead of pciehp_unconfigure_device(): https://lore.kernel.org/r/20231015093722.GA11283@xxxxxxxxx/ https://lore.kernel.org/r/ZzJm6QrQyT48jGuN@xxxxxxxxx/ Thanks, Lukas
