Thomas, thanks for cleaning that up. You may add to patches 03/04: Acked-by: Helge Deller <del...@gmx.de> On a side-note, there is sadly no general function like turn_off_all_kind_of_runtime_hang_detectors() which turns off *all* detectors at once (including soft lockup detector). I've seen another detector complaing at runtime that we were hanging here. I would need to dig up more info if you are interested... Helge
