Hi all, We are trying to bring up two virtual wiphys on an AR9160 with not luck. Creation succeeds, but bringin up an interface on either wihpy locks up the target in what appears to be an infinite loop of warnings. More details follow: - Hardware phy0: Atheros AR9160 MAC/BB Rev:0 AR5133 RF Rev:b0 mem=0xc8d20000, irq=5 - Wiphy creation # echo add >> /sys/kernel/debug/ath9k/phy0/wiphy # cat /sys/kernel/debug/ath9k/phy0/wiphy primary: phy0 (INACTIVE chan=0 ht=0) secondary: phy1 (INACTIVE chan=0 ht=0) addr: 00:00:00:00:00:00 addrmask: ff:ff:ff:ff:ff:ff - Bring up interface iwconfig wlan0 essid cozyssid1 ifconfig wlan0 up Device locks up. Logs at the bottom of this e-mail. - Versions tested version d41229637fb42737ff792271b8f0ac9752de9cb8 (wireless-testing HEAD as of jun 30 2010) version 062bee448bd539580ef9f64efe50fdfe04eeb103 (wireless-2.6 HEAD as of jun 30 2010) version e40152ee1e1c7a63f4777791863215e3faa37a86 (linux-2.6 v2.6.34 ) We have a dedicated target for this, so we can quickly test patches or diffent kernel versions. Does anyone know if virtual wiphys should work on the AR9160 ? Thanks!
