Could you send us a complete trace ?
One way to get one is to use netconsole (provided you have another
machine )
grep NETCONSOLE .config
CONFIG_NETCONSOLE=y
Add on your boot command
netconsole=4444@....168.20.108/eth0,4444@....168.20.112/00:1e:0b:ec:c3:e4
messages sent to host 192.168.20.112 udp port 4444, mac addr 00:1e:0b:ec:c3:e4, on eth0
then on 192.168.20.112 start a netcat listening on udp port 4444 to get
a copy of messages.
netcat -l -u -p 4444
