The bad host is an APU ("AMD GX-412TC SOC") with 4 GB of RAM, one of the
good hosts is a "Xeon(R) CPU E3-1246 v3" with 32 GB of RAM. Both are
somewhat dated due to the darn iptables => nftables migration and still
run Debian buster, kernels are identical (a 6.4.12 built in the same
container than the 6.4.12 that works and the 6.5 that misbahaves on the
test VM), system configuration is from the same ansible playbook, but of
course there are differences. But my strongest bet is some weird CPU
type issue becuase that's the most blatant difference.
Greetings
Marc
