Hi David, according to the kernel log you provided the crash occurs in ieee80211_wake_txqs(). Could you please run gdb in order to identify the point where NULL pointer dereference occurs? E.g: $gdb mac80211.ko $info address ieee80211_wake_txqs $l*(<func addr>+<offset>) offset is 0x1e3 in your log Regards, Lorenzo
