Argh, okay. I guess, you had batman-adv on your laptops already running and the wifi interfaces up when starting batman-adv on your laptop, right?
Could you have a look, if this kernel panic also occures, when you start batman-adv on your router first? I'd like to know if this might be related to the bug stated here [0].
If I remember right, then you were saying that you're using the 8.09.2 release of OpenWRT. Otherwise you could have activated "Compile the kernel with symbol table information" under "make menuconfig" --> "Global build settings" to add some function names to those nice numbers :)
Or does anyone of the others know if/how ksymoops could be useful/used in this situation to extract the function names afterwards?
Cheers, Linus
