+Hi,
+
+Currently I'm trying to resolve the following mysterious issues caused by the
+ath9k driver on the ar913x based devices:
+
+1. In some cases the ethernet interface goes down for a short time
+after'ifconfig wlan0 up'.
+2. Sometimes the device simply reboots itself after 'ifconfig wlan0 up'.
+
+After I have added some printk statements into the code, I noticed that the 
+ar5416 and ar9100 devices use the same initval arrays currently. I assume 
+that they requires different initialization, because we have different 
+arrays for them.
+
+Although I have no detailed knowledge about the evolution of the ath9k devices,
+but the version checking macros for ther AR5416 cards seemed weird enough, so I
+have replaced them. Unfortunately, this leaded to very bad performance with the
+ar5416 cards I have, but the driver was working on the ar913x boards.
+
+After some digging, I have found an interesting ifdef statement in Sam's current
+HAL. In his ar5416Common initval array, this ifdef conditionally selects the
+right RTC register offsets for the ar5416/ar9100 devices. The strange thing,
+that in the ath9k driver the ar5416 specific RTC register offsets are used in
+the ar5416Common_ar9100 array, while the ar9100 specific offsets are used in the
+ar5416Common.
+
+After I have renamed the arrays and tested the ath9k driver with the new
+settings on the ar9100 devices, the strange problems I have mentioned above
+disappeared. Unfortunately I have no ar5418 devices so I can't test them, 
+but they are using the same array as before so this change should not 
+cause problems on them.
+
+Regards,
+Gabor
