E.g. kernel, QEMU, 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.
