So all these files are just noise. Yeah, and also, looking at your previous mail, stuff like: /sys/bus/mc6/devices/dimm0 /sys/bus/mc4/devices/dimm0 doesn't make any sense: why is mc* directly under bus? It should be under ...bus/edac/mc/... We'll have to clean it up carefully, when there's time. > But ... we are at -rc5.

Yeah, after sleeping on it I see it the same way - band-aid it now and clean it up properly later. Thx. -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply.
