Hi I guess, I'm having exactly the same issue, but using an Atheros AR2315 SoC and the ath5k driver and an older compat-wireless packet (2011-07-24) with a 2.6.37.6 kernel.
I have the same setup, hostapd running on wlan0 and a mesh network (80211s) on mesh0. Both interfaces are the same phy0 and are bridged with a br0 interface. Sometimes the setup seems to work, but often the whole node crashes (most likely the kernel) after a few minutes and reboots. Any idea? Thanks!
