[I intentionally switched off line wrapping, since it renders the given information
inedible]
Hi Neil,
sorry for the delay. Meanwhile, I updated to mdadm 3.2.6, and recreated the initrd.
Since I do the recreation on a regular base, no data salad appeared, but the initial
issue persists. I trigger checking the related md on each manual intervention.
Hence approaching this again.
That's a typical boot sequence:

Today, /dev/sdb1 of /dev/md0 vanished. Re-adding and checking doesn't revealed
any error, but it would be cool to get to the bottom of this, as re-adding some
lost partitions to the md every second day *is* a real PITA.
What could I do to help resolving this issue?
Thanks in advance,
Pete
