I was just investigating the same thing just now. So that saves me some
tracking down the culprit :-) .

My main qemu is living as a "board" in my boardfarm (also doing nfsroot)
as well as my d1 nezha with nfsroot was affected.

Though my board is stuck in some failure loop with both the journal- as
well as the timesyncd service failing again and again. And I haven't
figured out how to get logs without a working login console yet.
