On an impulse, I tried shrinking the RAID arrays to only have two
devices each without being degraded; I updated the initramfs and
unplugged the SSD too, just in case. The bug persists, so we can rule
out the three-legged array as a cause/trigger (I have no idea it if was

Not sure I mentioned it, but the bug occurs before LUKS stuff happens;
at least, I don't get asked for the passphrase.
Any sufficiently advanced technology is indistinguishable from a yo-yo.
