[ath9k-devel] AR9380 on Kirkwood 88FR131

[Daniel Golle <dgolle@allnet.de>]

Hi!
I'm trying to use a Senao EMP7606 module (AR9380) on a Marvell Kirkwood
88FR131-based board running OpenWrt r32511 with Linux 3.3.8 and
compat-wireless-2012-06-14.
I'm unable to figure out the reason for the card not working properly. Please
advise me on how I should go on debugging/investigating the issue.
ath9k_hw_reset is quite complex and I can't figure out why it returns -EIO.

Initially, everything seems to work fine (scanning, creating interfaces,
hostapd/wpa_supplicant, ...), it fails once there is any traffic:
