custom kernel and acpi/thermal settings


this isn't so much slackware specific as it is general linux related, but using the default huge slackware kernel included with 13.1, acpi reports cpu temps of about 55 celsius

i always like to run my own kernels though, and using the latest stable kernel, i have compiled one using what i believe is necessary for my hardware, and everything works as expected except that acpi reports my cpu temp as 80 celsius at idle, causing my fan to be running constantly

so without simply using the generic config included with slack in the newer kernel, what do you think might be causing the thermal issues?

i used diff on the two configs and the output is over 5,000 lines, so thats not a huge help, and im really not even sure what to be looking for

the cpu is an intel i7 720qm, so if anyone might know any specific settings for that processor type needed for acpi to interface with it properly that would be much obliged

here is my config for potential review: http://pastebin.com/jh3wwa17

also, if i disable acpi entirely, the fan operates as normal but i cannot get readings obviously

thanks


update: during some troubleshooting, i had switched clocksource to jiffies, this was the cause of the high temperature readings

Thanks for the solution & double thanks for using a
pastebin -- Those 2935 lines would have made reading your post very unpleasant. I only wish I could legitimately give you double rep points.
