Re: [Cooker] A thing called kapm-idled is taking over my machine !
I have read the thread. A few points : Can an application spoof 'top' into reporting a CPU usage that is not really there ? If it is just 'reporting' the NOT CPU usage, how does that make its way to 'top' as actual CPU usage. A bit of perseverance and, like the inetd, you can get it to the much healthier state of priority = -1 and CPU usage of 0%. So what have I just done. Stopped the CPU idle loop or stopped the APM daemon from hogging the CPU ? Given the responsiveness of the system I don't believe that the idle loop has been affected, and given APM all works then nothing has happened to it either ! According to the kernel mailing lists the name kapm-idled was just put there to stop people complaining that kapmd was using too much CPU ! Surely a better fix would have been to look into why kapmd was using / reporting such a high CPU usage. If it is just 'reporting' that the system is idle why bother ! Surely the big black bar on 'gtop' is far more comforting than 40 - 80% CPU usage !!! I realise this is out of Mandrake's remit, but it is certainly confusing. Do Red Hat have a newer kernel with a better fix ? Please observe - Red Hat's Rawhide 2.4 kernel DOES NOT display this perverse behaviour (their kapm-idled has a PRI of -1 and CPU of 0), so why does Mandrakes ?

Re: [Cooker] A thing called kapm-idled is taking over my machine !
> you now what idle mean ? There's no need to be rude ! All I was doing was reporting that on the Mandrake 2.4 kernel gtop reports kapm-idled as using somewhere between 40 and 80% CPU while on the Red Hat 2.4 kernel it is reported as 0%. And it would appear that I'm not alone. I could post a report to the Kernel list, but since it happens with the Mandrake kernel but NOT the Red Hat one I thought I would start with the Mandrake list. If it "doen't do anything" then why is it using 40 - 80% CPU resource ? This was supposed to be a constructive observation !

Re: [Cooker] A thing called kapm-idled is taking over my machine !
I noticed it first on kernel-2.4.0-0.12mdk but it also happens on kernel-2.4.0-0.13mdk. But, as I said, it does not happen on kernel-4.0.1-37 from Red Hat. Where are these daemons started ? Is it possible to stop them ? and if so how ??? Someone at work managed to get it down to 0% by doing loads of 'this and that' !! But it started up again ! I think it ought to be renamed kapm-idled-cpu-snatcher !

So what is kapm-idled ? and why does it use so much CPU resource ? kapm-idled is related to power Management in the kernel . In a cooker fresh install (kernel 2.4) , i got it work correctly (SW stat with 0% CPU) What kernel version do you have ?? > > Owen > > P.S. My work PC still runs like an old dog !
