Red Hat Bugzilla – Bug 139076
"Temperature above treshold".
Last modified: 2015-01-04 17:11:55 EST
This is a problem I've been having some some distros when I switched to kernel 2.6. As soon as I start CPU intensive tasks, I get messages from my kernel that my temperature is above treshold and that the cpu will run in modulated clock mode. I'm not sure what causes these messages, but they are quite annoying (show up al least every second in my terminal). When I first had this (wasn't using Fedora yet), I checked my BIOS, where the temperature read 70-80°C. Lm_sensors however said the temperature was about 30°C (as I would expect it). Also, the CPU's heatsink doesn't feel that warm, nowhere near 80°C. This problem went away by itself, but now that I switched to Fedora, it's back. So is my BIOS causing this, or is it the kernel ? I've tried updating the BIOS several times, but nothing changes. Both my CPU and MB are Intel.
Let me get a bit deeper into this, as I'm seeing this too. I run FC3, and just transitioned from 2.6.10 to 2.6.11 (both stock pre-built kernels) and transitioned from regular to SMP kernel at the same time (for non-interesting reasons, as I'm still running the same uniprocessor system). When I did this, I started getting the errors spammed to every terminal, so I checked the code. This alert is sent out as KERN.EMERG. It is NOT an emergency notification, and should not be sent out as such. I understand why it would be considered harmful to run hot, but those of us who choose to run a bit hotter than spec wish to continue to find out systems (be they server or desktop) usable. Lowering the level so that users are not tempted to shut of *.emerg reporting would be wise.
i do have the problem on an MSI Neo3 main board after i have upgrade the bios i do not have the problem. the only thing is that it does not swithoff the motherboard,even if i add acpi=off or acpi=ht in the grub.conf file. any idea is the most wellcome
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you.
