Attempt to assemble RAID times out and drives go busy?

["David F." <df7729@xxxxxxxxx>]

If I start kernel 5.15.60 with parameter "nodmraid" then attempt to
run the script below, it will fail (attempts to assemble but it will
timeout and sda/sdb become busy).  Yet, loading through the udev rules
the raid is created okay.  Although dmraid overtakes the mdadm.

Here's the script that always worked until updating to both 5.15.x and
all the various libraries and utilities.

#! /bin/bash

if [ ! -e /proc/mdstat ]; then
    echo "Software RAID drivers not loaded"
    exit 0
fi

if [ ! -e /etc/mdadm/mdadm.conf-default ]; then
    echo "Default config file not found in /etc/mdadm"
    exit 0
else
    cp /etc/mdadm/mdadm.conf-default /etc/mdadm/mdadm.conf
fi

mdadm --examine --scan >> /etc/mdadm/mdadm.conf
mdadm --assemble --scan --no-degraded -v
