#13452 assigned defect
DIR-825 wlan phy1 invalid mac address

Description
After upgrading to AA 12.09 on a DIR-825 rev B2, the second radio doesn't come up and the kernel log shows:
ath: phy1: eeprom contains invalid mac address
I assume this is related to the changes in r35731.
I reverted to 12.09 RC1 on the same router and the second radio comes back up with the correct mac address, so the caldata partition doesn't seem to have been corrupted.

I checked again and it turns out my memory didn't serve me correctly. Here is the mac address layout for stock firmware version 2.06EU:
lan 4d wan 4e wlan0 4d wlan1 4f

Just flashed r41353 and the second radio works. I still have these error messages in the log:
ifconfig then shows the real mac address, not the random one previously generated.
Speaking of mac addresses, I noticed the following pattern: br-lan, eth0 and eth0.1 have the same mac, ending in 4d (in my case), then eth1 is 4e, then wlan0 is 4d again and wlan1 is 4f. I distincly remember that the stock firmware assigns 4e to wlan1, but I don't know what eth1 gets. Not a big nuisance though.
All in all, I think the ticket can be closed and #14563 as well.
