I'm not sure how I should interpret that:
"Sun 2021-02-21 21:20:11 CET���������Thu 2021-04-15 16:13:35 CEST" seems to be the
timespan since the last succesful boot until the catastrophe.
But then "Thu 2021-04-15 17:14:12 CEST���������Thu 2021-04-15 17:12:08 CEST" makes no
sense. The boot that failed was immediately after the catastrophe, and the next
and only other time I booted after that was (succesfully) a few minutes later,
definitely not at 17:14:12.
I'll attach both the output from both "journalctl -b 0" and "journalctl -b 1".
