Hi everyone, hope you are doing well.. I been noticing some instabilities with the bridge on 13-STABLE (not sure when it started). Environment is as following: - kernel:FreeBSD tucho 13.1-STABLE FreeBSD 13.1-STABLE #21 stable/13-n251571-2ff5f3e7d159: - bridge0 members : igb0 and vtnet0.1 ( jail with vnet). - bridge0 no STP/RSTP - igb0 connect to FBSD based router. - No PF nor IPFW. Symptoms: Bridging: sometimes bridging works as expected, can ping attached router on igb0. Bridging: randomly stop doing any switching. traffic still can be seen with tcpdump. kernel panic: if bridge is delete, got a kernel panic. The following commands are sufficient to panic the system. ifconfig bridge create name test ifconfig test up ifconfig test addm igb0 addm vnet0.1 ifconfig test stp igb0 ifconfig test 192.168.3.100/24 ping -c4 192.168.3.1 ifconfig test destroy Still cannot save the panic as the machine reboots and there is not core and crash files.. Any recommendations on how to catch it are welcome.. Santi
