I get a kernel panic when i'm using if_bridge bridge0 interface with 2 virtuals (ng_eiface) and one physical (xl0). The panic message is: sbflush_locked: cc 0 || mb 0xc1aa2400 || mbcnt 512 How-To-Repeat: kldload ng_ether kldload ng_eiface #create a bridge & 2 virtuals ifconfig bridge0 create ngctl mkpeer . eiface hook ether ngctl mkpeer . eiface hook ether # give them some settings ifconfig ngeth0 ether 01:02:03:04:05:00 ifconfig ngeth0 192.168.1.2/24 ifconfig ngeth1 ether 01:02:03:04:05:01 ifconfig ngeth1 192.168.3.2/24 ifconfig bridge0 addm ngeth0 addm ngeth1 addm xl0 ifconfig bridge0 up # Count traffic using ipfw ipfw add 1 count ip from any to any in recv ngeth0 ipfw add 1 count ip from any to any out xmit ngeth0 ipfw add 2 count ip from any to any in recv ngeth1 ipfw add 2 count ip from any to any out xmit ngeth1 ipfw add 3 count ip from any to any in recv bridge0 ipfw add 4 count ip from any to any out xmit bridge0 and wait a few seconds for kernel to panic.

C> C> Traffic flows via physical(xl0) when i shoot these commands. It looks like your ngeth interfaces aren't connected to any graph. Is that true? Is it essential that ng_ether node is loaded? You don't use it in your example. Actually, a bug in interoperation between ng_ether and if_bridge has been fixed in CURRENT. It is not yet merged to RELENG_6. However, your panic looks different. That's why I am asking about backtrace. -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPE

Keep in mind that when i 'm creating/altering netgraph nodes at the same time i have ~500 connections and some daemons running (samba,isc-dhcp on physical, apache,mysql).
