I assume that's a mis-paste as they should be ^ 1.

That's really helpful!  Please keep the file there for the moment.

So you got associated constantly (you made it to RUN) but then you didn't hear
any beacons and dropped off again.  Rince and repeat.

What's more important is what's following:
ieee80211_sta_join: BSS c8:7f:54:b5:d5:f0: 2GHz channel, VHT info; ignoring
and the firmware crash following with the 0x5/0xf hcmd.

Can you please send me your AP details (in private if you want).
Also if you disable 11ac and 11n again, can you then
ifconfig -v wlan0 list scan
and give the output for your 2.4Ghz and 5GHz SSID(s)?

I intially thought it was a channel switch from 5Ghz to 2.4Ghz which
causes the problem for the firmware panic;  could very well be that the
APs supporting VHT on 2Ghz causing the trouble (or both).

Lots of health,
Bjoern
