Could this situation be attributed to iwi driver or maybe wlandev? I've seen something which might be related. Using a iwn(4) device for some time my -CURRENT box locks up completely, no reboot, no panic, no ctrl+alt+esc.. The last message I see is from net80211 sending a power notification wakeup message after returning form a background scan. Still digging around, trying to find the cause. -- Bernhard
