Well... it took about a week to finally find the node creating this
problem. As before, it's failing hardware that caused the issue.

When this happens every node in the net is repeatedly showing that
message. It is not the same with any "loop symptom" I believe... At
least I've never seen this happen on every node being caused by
something else.

I really would like to find out more about how this condition comes to
happen and how to diagnose and prevent it. The whole batman-adv cloud
dies when this happens and it's a pain in the ass to "debug".

All the failing routers are WR842ND. There are many more of the same
model working just fine.

I now have three routers which produce this symptom, so if anyone who
can understand the problem better is willing to test, I can set up a
dedicated mini-test-bed.

Cheers,
