Has anyone seen a crash like this?
I’ve got two BPI-R3 running the latest snapshots of OpenWRT; there’s a mesh network between them (wpad-mesh-wolfssl to manage it; the hostapd in this trace is from that package)
It crashes frequently, I suspect when devices move between the two APs. It’s worse with 802.11r turned on.

While I’m at it, any way to get it to reboot into the same system? It wouldn’t be so bad if I didn’t have to go reboot the device manually afterward.
