It works at least for me, as AP and as STA...

Thanks, good to hear! :)

Check:
- PCIe related power managment - ASPM.

That sounds most suspicious. Will try to see what can be done in the BIOS or if disabling ASPM in the kernel helps.

- WiFi related PM. "iw dev wlan0 get power_save"

That would only affect STA and IBSS mode, right?

- defect device?

Having the same problem on two setups... maybe but it's unlikely...

I have a AR9287 PCI-Express card which is behaving more than weird with
kernel 3.2 and with the current (3.10.4-1) backports drivers: It can't
connect to APs (many reconnects), with hostap it _seems_ to work as an
AP, but no beacons are seen and no stations can connect, similar in
ad-hoc mode, and when bringing the interface down the whole system
freezes...

Is it regression? Are there any working kernel version?

I have tried with 3.2 clean (Ubuntu 12.04 default) and with the mentioned backports version. If you point me to a known working backports version I can try it.

Or - can anyone recommend a good half size PCI-Express card that works
well with ath9k?

If you wont to bay some new toy, then take a look here:

I would take AR9462, there are some interesting highlights ;) (suddenly
I do not have it right now)

integrated bluetooth 4.0; 8bit Spectral Scan?

Thanks!
