I'm glad you sorted it out. :)[..]
It's taken a week to set it all up again, but rock solid and while still not solved (unlikely to happen while affected numbers are small) it is no longer my problem.
Please, mark the discussion as "solved" manually adding the text tag "[Solved]" at the beginning of the subject of the first message; for example:
Happy Debian ! :)[Solved] Crashes and freezes in Linux with (some) Ryzen CPUs
