hi,
 wonder if you could try one more test for me.
 With the other (echo BEFORE / echo AFTER etc) tracing still there, change the
   /sbin/udevadm settle --timeout=$MDADM_DEVICE_TIMEOUT
 to

   /sbin/udevadm --debug settle --timeout=$MDADM_DEVICE_TIMEOUT > /dev/kmsg 2>&1

 I found there is a case where "udevadm settle" can exit before the queue is
 empty.  It seems like a very unlikely scenario, but it seems clear that
 something "unlikely" is happening.
 I'm hoping to see
    timeout waiting for udev queue

 appear in the logs when this runs.

 If you could add that and post the 'dmesg' output if you ever get that
 message - or maybe even if you don't - that would be very helpful.

Thanks,
NeilBrown
