kern/160391: [ieee80211] [patch] Panic in mesh mode

Will provide dumps soon.

But yes, effectively, two physical radios on a single board.

Each configured in mesh mode. 

When they are both configured the same (channel/meshid/etc), and see each other, bad things happen. - Easy fix is to MAC filter.

When they are both configured differently (channel/meshid/etc), and see each other, via the network, bad things happen. - Easy fix is to MAC filter.

Interesting phenomena I am tracking down...sometimes the local and peer addresses are three characters vs four...and then of course its b0rkeD...a reboot sometimes cleans it right up, and things run...

Finally, there's no mechanism to manually flush out the mesh info, yet, so I also noticed that it appears the routes just stop updating...

I've been too busy to root cause many issues, and have only focused on the show-stoppers...but I really need to...

Hi Edgar,

Can you please provide;

* A dmesg, just so we can see what/how many radios;
* what do you mean by "create two mesh nodes" - do you mean two mesh
nodes on the same board, one on each radio?

Thanks,


Adrian
