Comment (by lordgilman):
I've been working with the author of the EA3500's wireless driver on the
linux-wireless mailing list. You can see the latest message in our
correspondence here:

I've recompiled hostapd with full debugging support and captured the logs
in that email for when the disconnects happen. No drop ever looks exactly
the same but they all look like the WiFi device is unable to respond to
the EAPOL message in time. This would explain why certain devices work
fine on the same hardware while others are perpetually dropping
connections, and why molocho's findings in comment 32 show that switching
to a quiet channel doesn't help out here.
The timeouts for all of this stuff are hardcoded in hostapd, in
src/ap/wpa_auth.c. I am tempted to get a patch to change these, but the
fact that they're not configurable at runtime makes me a bit wary that
there might be a good reason for those constants. I'd appreciate it if
anyone from the OpenWRT project who's familiar with the workings of WPA
could give some opinion here. If this patch isn't a bad idea it might be
a good idea to ship the Audi Kirkwood binaries with a patched hostapd.
