Subject: 2.6.23-rc8: cannot make netconsole work

I finally decided to try netconsole in attempt to get some more information 
why my system does not resume (but that is different story). But I cannot 
make it work - it does load but I see no traffic flowing ever. This is 
notebook with e100 driver and it works just fine for normal traffic. 
netconsole is currently compiled as module, loading it I get:

sudo modprobe netconsole netconsole=@...h0,@/ 

[ 2395.838094] netconsole: local port 6665
[ 2395.838126] netconsole: interface eth0
[ 2395.838132] netconsole: remote port 6666
[ 2395.838140] netconsole: remote IP 0.0.0.0
[ 2395.838150] netconsole: remote ethernet address ff:ff:ff:ff:ff:ff
[ 2395.838175] netconsole: local IP 192.168.1.8
[ 2395.843798] console [netcon0] enabled
[ 2395.844722] netconsole: network logging started

but I cannot see any packet flowing via eth0 not can I catch anything on 
remote side using netcat. This does not work when I add explicitly source and 
target addresses either:

pts/0}% sudo modprobe netconsole netconsole=@....168.1.8/eth0,@192.168.1.5/
{pts/0}% dmesg | tail
[ 2427.128947] device eth0 left promiscuous mode
[ 2427.129005] audit(1190970818.972:5): dev=eth0 prom=0 old_prom=256 
auid=4294967295
[ 2541.831721] netconsole: local port 6665
[ 2541.831756] netconsole: local IP 192.168.1.8
[ 2541.831763] netconsole: interface eth0
[ 2541.831769] netconsole: remote port 6666
[ 2541.831776] netconsole: remote IP 192.168.1.5
[ 2541.831787] netconsole: remote ethernet address ff:ff:ff:ff:ff:ff
[ 2541.838832] console [netcon0] enabled
[ 2541.839964] netconsole: network logging started

config and attached.

TIA
