Hi, Florian Your commit 98d1bd802cdbc8f56868fae51edec13e86b59515 (netfilter: xtables: compute exact size needed for jumpstack) introduced the following kernel warning during boot. It looks like the if check inside mark_source_chains() isn't correct, this causes calldepth not increased as expected, but I don't have time to dig this. Let me know if you need more information.
