Enabling bridge while interfaces have link freezes console
Installed 2.4.2-DEV CE (snapshot from about an hour ago) on both a VM and XG-2758.
If you try to create a bridge with interfaces that have physical link the entire system freezes and hangs.
You CAN create a bridge if the interfaces are in a state of "no carrier" (no physical link).
I installed pfSense on a SG-2220 and tried to bridge two VLAN interfaces on a physical interface with no link. It worked just fine but eventually encountered the same problem. It's possible that even a bridge with no links to it's member interfaces may eventually freeze as well - I haven't been able to verify that yet.
VLAN bridge test was with 2.4.2-DEV Factory.

This may be an issue on my end, with VMware...it's possible I saw what appeared to be the same issue on the XG-2758 because it dropped network connectivity while I was remotely consoled in. The SG-2220 that I had setup VLAN bridge on before trying this on the XG-2758 may have appeared to break because my network connectivity was hung once the XG-2758 bridge was made.
