Hi,
I am using ath6kl - AR9374 chip in our product which has ARC platform.
wireless drivers used are from
https://github.com/senthilb/ath6kl-compat-wireless/tree/olca-3.2.2
Steps followed
1. Inserted compat.ko, cfg80211.ko, ath6kl_usb.ko
2. Kernel on the platform is 2.6.26 + ARC platform
3. I could see wlan0 interface
4. Ran wpa_supplicant and noticed that module is associated with the router
NETGEAR WNDR3700 and TP-linkTL-WR841N
5. Kernel panic observed as Misaligned access (ip_table + 0xac) triggered,
this is after router issued IP to the ath6kl wireless module.
Issue happens only when the router is operating in 80211n mode, issue
vanished when the mode is b/g.
