If there are issues they are bugs. 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. -- Regards, Pavel Roskin
