Thanks.  I see it now.  So we have a bug affecting AR9220, plain and
simple.

I can confirm that 0xdeadbeef comes from the chip, not from some random
place in memory.  Even the supported Ubiquiti SR71-15 returns 0xdeadbeef
when reading from the register 0x00ac (AR_IMR_S2).

The fact that SR71-12 only works if installed in a slot below SR71-15 is
very intriguing.  I checked the modules with nm for possible static
variables, but I cannot spot anything wrong.  I'm going to try
mmiotrace.
