[gentoo-ppc-user] OT: thermal management diff 2.4 vs. 2.6
Hi list, since i dont't know where else to ask this question i figured i might as well ask it here. i'm running gentoo on my tibook 550 (powerbook3,3 that is in kernelspeak) and noticed that with a 2.4 kernel as well as under macos the fan hardly ever kicks in, even when the computer gets quite hot while with the 2.6 kernel the fan wouldn't stop running. while this aproach is probably bying me some more lifetime for my computer, it is seriously annoying not to have at least an occasional moment of silence when sitting in front of the box. i already tried searching the kerneltree for suspicious expressions like fan.*control and such but so far without success (meaning i found only acpi-related stuff). can someone please give me a hint where else to look or even where else to ask this question? any help is appreciated! thanks in advance and best regards, alexander pgphsJlYyASOe.pgp Description: PGP signature

Must be grmelins in there or something. echo 10 /sys/devices/temperatures/limit_adjust if you want the fans to kick in at 60°C instead of 50°C. These are Tibooks (as opposed to newer Alubooks) so they do not have software temperature control, no? Stefan -- If it was so, it might be; and if it were so, it would be; but as it isn't, it ain't.

Try to load the therm_adt746x module. If it fails to load, you're right :) Oh, of course therm_adt746x won't load, sorry for not mentioning it. There is as far as I know no option in the kernel config for thermal management on these machines. I am clueless as to why is the fan behaving differently, it simply shouldn't.

I'm not an expert here, but could it be the kernel is not using some kind of CPU idling when it's not busy? Maybe the CPU is actually running hotter than it used to. Just an idea, may not be founded in fact. ;) -- // Carl Hudkins :: Jabber [EMAIL PROTECTED] :: PGP 50238D9E // // ==] What would Jeeves do?
