I have three nodes running OpenWrt r16484 (SVN) and batman-advanced r1298. All nodes show each other in originators. batping gets host unreachable for all relationships, and the host unreachable messages come very quickly, maybe 1000/second. Here is a log sample, log_level 4. log_level 11 doesn't show anything.
The setup I'm using worked fine with r1176. Using ahdemo.
