Kernel panic when brouted packets reaches iptables NAT table

Hello,

This might not be the right place to post this
question on, but I believe someone here would have some
clue.
 
I faced a problem that causes Linux kernel panic while 
configuring transparent bridge proxy. This is very 
repeatable. Here"s what I did:
 
 
 1) Create A simple bridge (eth0 - eth1). No STP. IP is
   assigned at bridge interface(br0) only.

 2) Broutes packets that should reach transparent proxy 
 
 ebtables -t broute -A BROUTING -p IPv4 -i eth1 \
   --ip-dport 80 -j redirect --redirect-target DROP
 
 3) Redirects the packets at iptables, NAT table, 
    PREROUTING chain
 
 iptables -t NAT -A PREROUTING -p tcp -dport 80 \
    -j REDIRECT --to-ports 3128
    
    
Kernel panic takes place at iptable redirection rule which 
redirects packets to squid instance listening at port 3128.

Could anyone tell me what is wrong with my setup? -j ACCEPT
instead of -j DROP at 2) seems to solve this kernel panic
problem but I need to broute this proxy traffic.

Any kind of response would be appreciated.

Best wishes,

Jinsuk Kim
