Since reporting this problem I have tried running both systems on one
switch, and performed a kernel and userland build from stable.
The behavior is unchanged in both cases.
help? Am I really that stupid? This was working on 3.9

Two systems running 4.0 GENERIC#1107 i386 on bge drivers.
They are being used as vpn servers
They are each jacked to their own cisco 2950. The switches are connected
with to each other xover cables. Each host can see the others carp
traffic, pf is configured to quick pass carp traffic. both system
insists on being master. I can ifconfig the desired slave to backup
state but after a couple of seconds it pops back to master.
I am using sasync, the tunnels are all up and traffic flows as expected
though I think that has more to do with pfsync keeping the state tables
synced, and the internal interfaces are behaving correctly.
The inside ifaces are jacked into the same switch, but shouldn't I be
able to be jacked into two separate switches?
Erm ... ? I am in GMT + 8, tomorrow morning I will try putting the
slave on the same switch as master, but that or course creates a single
point of failure.
Any other hints?
