Overheating after kernel upgrade

Today I did an upgrade of my Acer Aspire 7720. There were a good number of packages upgraded ... about 190.
After the upgrade I rebooted and started to work as usual. After a few minutes the machine shut down on it s own. It impressed me as odd but I rebooted it again... and sure enough after a few minutes it went down.

Then I realized my laptop's keyboard was way too hot !!

After letting the machine cool down for awhile I reviewed all tha pacages upgraded but could not see anything capable of creating the problem but the latest kernel upgrade.
I downgraded it from 2.6.31.4-1 to 2.6.30.6-1 and now things have gone back to normal, therefore verifiying the culprit of the problem.

Is anyone else experiencing similar problems? Should I report this to our kernel maintainer (I'm presuming we have one ) or is this an upstream issue?

Re: Overheating after kernel upgrade

Possibly related to <http://bugzilla.kernel.org/show_bug.cgi?id=13967>, I might guess.

lm_sensors may have stopped working on your machine, meaning fancontrol may be failing.

*EDIT:* Oops! Forgot to mention the 'fix' described for this regression: add "acpi_enforce_resources=lax" to your kernel boot parameters.

pointone,

Thanks for that reply. You may be very well on the right track because I noticed the fun was not running ... or at least I was unable to hear it even if I would place my ear very close to the fun exit.
