I had vap1 on an ath10k NIC, and wlan2 also existed. I deleted
the vap1, and very shortly afterwords, the firmware crashed:

Is there any way short of reboot to recover from firmware
crash currently?
Thanks,

This dump looks suspicious. Are you using vanilla kernel or do you
have a ath regulatory hack patch from OpenWRT applied? If so the
channel scan list is not sent to the firmware and this will cause
firmware to crash.

I've posted some patches recently and are currently under review. You
can try applying them yourself and test it.

I had some of my own patches in the 3.11 kernel. I tried the vanilla ath
kernel from github and it crashes when adding a second station.
Can you (or whoever has firmware access) get something resembling a
stack trace from the firmware dump to see where it's crashing?
Has anyone been able to successfully use more than one station with
ath10k so far?
Thanks,
Ben

I don't have access to the firmware to do such a thing.

Well, it works for me on ath branch.
I'm able to successfully associate 2 STA interfaces or a couple of AP
interfaces through hostapd's multi bssid support.
One thing you should know - it's impossible to associate with two
ath10k STA interfaces to the same AP. This is a firmware limitation
and I'm guessing you're trying to do that because 'Failed to add peer'
is visible in your other logs.

I was trying to associate to the same AP. Looks like the firmware
is just too brittle at present...

Can you add that to the wiki, please? It would be good to document all
these kind of special cases.
