I would like to have a different hardware/driver combination to try

I don't mind doing a bit of driver hacking so long as the basic support
is there (I think it's mostly the ability to set a BSSID mask and rxfilter
accordingly).
Your best bet is to test against mac80211_hwsim, that would rule out
any hardware. I think Jouni and Johannes have also a way to get the
devices to talk to each other. Perhaps some documentation of that on
the kernel Documentation/networking/mac80211_hwsim/
Ok. I'm trying to hack slub to give me a better stack trace of where
the skb was deleted. If that doesn't turn up anything obvious, then
I'll go read up on hwsim.
Are you aware of any DMA issues that might cause ath9k to write into
places it should not? Previously, I've seen a lot of errors in
the logs about ath9k not being able to stop DMA in time, but I haven't
seen those while reproducing the memory corruption.
Thanks,
