Hi guys,
I'm having an issue with Mint 19 (MATE), recently installed.
My i7-4700MQ will boot just fine but after some minutes (random as far as I can see) the CPU freq will be at the max value. That could be normal under heavy load but it doesn't scale down anymore until I reboot the pc, even when all cpus are idling.
I checked cpufreq and it seems to be doing fine. For example this is one of the cores (they all look the same):
analyzing CPU 1:
driver: intel_pstate
CPUs which run at the same hardware frequency: 1
CPUs which need to have their frequency coordinated by software: 1
maximum transition latency: 4294.55 ms.
hardware limits: 800 MHz - 3.40 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 800 MHz and 3.40 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 3.39 GHz.
The min and max freq values are fine. The governor is fine (using powersave, I can't try ondemand because cpu > Sandy Bridge).
I was running Mint 17 until now and AFAIK the cpu was fine. I fear that MATE is causing the issue but I really have no idea. I was using KDE before.
Any ideas? Thanks in advance!

Re: CPU freq not scaling down
Posting back following code result as indicated here will be very appreciated.
I don't think it is a DE (Mate), distro (Mint) or edition (LM 19) problem. I think it is related with kernel, BIOS/UEFI settings (if you have installed in UEFI mode>Boot mode UEFI, not CSM or Legacy BIOS compatible /support,disable fast boot, secure boot,.. enable Intel SpeedStep...), Intel controller or graphic you are using (integrated Intel/discrete nvidia??).
Check
Any way, I must be wrong because my I7-4700MQ is Haswell not Sandy bridge.
PD: Laptop-mode-tools or others tools are useful to adjust such things but also need a well integrated kernel and BIOS updated. If errors or fails are reported in dmesg or you have already made permanent changes at booting (i.e.modified /etc/default/grub) you'd better do not use and uninstall those tools.
Code: Select all
inxi -Fxxnzr
Check
dmesg
and look for error, warning or fails (i.e dmeg |grep fail
). There are some kernel parameters you can try on booting but first confirm you have intel-microcode installed and the last 4.15 kernel (Update manager>View >Linux kernel....)Any way, I must be wrong because my I7-4700MQ is Haswell not Sandy bridge.

Re: CPU freq not scaling down
Hi,
Sorry it took this long to post a reply but I've been trying to understand the issue.
I've been playing a lot with the kernel version but I think it doesn't affect the issue. I thought I had fixed it but it seems like it still happens, although now it gets stuck at 2.5 GHz. No idea why, I tested too many things .
This is the result of inxi blabla:
This is the result of dmesg |grep fail:
My bios should be doing fine, I haven't touched it in a long time and it is already 5 years old. Of course if you think something could be wrong there let me know and I'll check.
I hope the info I pasted is useful, it doesn't really say anything to me.
BTW: I'm using a Nvidia with nvidia drivers. When I was in Mint 17 I was using the integrated intel gpu and optirun when needed. I do think that Mint 19 was working fine the first weeks but I can't prove that.
Thanks a lot for your help!

Re: CPU freq not scaling down
False alarm, it's back to get stuck at 3.20 without doing anything with the laptop (turn it on, wait some minutes, the freq scales to 3.20 and the poor fans blow and blow).
