[Voyage-linux] strange messages olsrd

[Xavier Martinez]

Hi!

We are developing a mesh network (olsrd) supported by a trunk network
in Spain.  We are currently using voyage 0.4.1 for the WRAPs of the
trunk network in ad-hoc and a mode. Until now, in the trunk we used
linksys with freifunk to give OLSR coverage to clients and WRAPS to
link nodes with dedicated links over an OSPF network and no problem.
OLSR nodes in the trunk are "forced" to pass over the OSPF network
using an openvpn connection (Interface tapX)

Recently, we tried to replace linksys for WRAPs with voyage 0.4.1 with
olsrd and openvpn installed. We configured the openvpn links and it
seemed to work properly. However, later we've realized that
/var/log/messages is flooded with:

kernel: ath_mgtstart: discard, no xmit buf

It happens in b and g mode (we have not tried a mode). However, WRAPs
that are in the OSPF don't show this weird behaviour. Any ideas?

Here are the olsr and interfaces configuration:
