No crashes after more than one hour of stress-ng on 1. 4 core amd64 Fedora 5.17 kernel 2. 16 core amd64, linux stable 5.17.15 3. 12 core intel, Fedora 5.18 kernel 4. 3 core aarch64 vm, 5.18.7-200.fc36.aarch64 I used standard firewalld ruleset for all of these and manually tuned conntrack settings to make sure the early evict path (as per backtrace) gets exercised.
