FreeBSD 6.0-RC1 #0
Generic
i386
>Description:
if_bridge is configured to load in loader.conf
bridge0 created in rc.conf:
cloned_interfaces="bridge0"
ifconfig_bridge0="addm xl0 addm bge0 up"
ifconfig bridge0 deletem xl0
or
once rules are loaded into pf, the bridge cannot be torn down. Even if the rules have been flushed and pf unloaded and all the interfaces are down
ifconfig bridge0 deletem bge0
hangs and is not killable.
When trying to unload if_bridge I get the following:
xl0: refusing to decrement non-positive refcount0for interface flags 256
>How-To-Repeat:
reboot and try again.
