Thanks for the steps to reproduce. That should help a little bit.

I don't have hardware here at the moment to test it. So cannot tell what the 
problem may be. Maybe another person has some free time to test it and check 
for a possible problem (but I don't think that anyone active has a WRT54GL).

what you could try is to setup the stuff by yourself using
 http://open-mesh.net/wiki/batman-adv-quick-start-guide and test which command 
may cause the problem (when it is batman-adv related).

No, JTAG and serial port are completely unrelated:
http://nuwiki.openwrt.org/oldwiki/OpenWrtDocs/Hardware/Linksys/WRT54GL#serial.port

But yes, you must build something. But it is highly recommended to have some 
serial console on embedded devices anyway.
