Hi,
I am trying to add cryptoapi support in wireless LAN driver (linux-wlan-ng for Prism based card) for my security project.
While doing so, I am getting a kernel panic. I am not able to debug it as there is no logging of any information related to kernel panic in the log files (/var/log/messages or /var/log/dmesg) when I reboot the system. I have attached the log below available on the screen.
Can anyone please help me in what can be possible error by looking at the log ?
I will greatly appreciate any help in this matter.
Regards,

You need to specify the kernel version you are running, plus all other
variables which causes this panic.
A objdump of panicing code (dev_queue_xmit ? not necessarily, what about
eip and register/stack, etc
that have scrolled out of the screen) will be useful. Use serial console
(documentation is present in
serial-console.txt) to get full dump information.

Don't call nf_bridge_update_protocol() for ARP traffic as skb->nf_bridge isn't
