It seems I can trace mac80211 which came with the kernel but as soon as I install compat I cannot record any events. Trace-cmd report says always that there are no samples. All debugfs entries are same and I can see event lists, enabled flags, etc. Even strace of trace-cmd are same for both cases. I am using 3.12.8 mainline kernel from ubuntu ppa. Does it have anything to do with module signing/tainting? Wojtek
