--- Comment #1 from Takashi Iwai tiwai@suse.com --- I haven't noticed it while using openSUSE-42.2 (but on a different one, Dell E7270). Could you check whether it happens with openSUSE-42.2 kernel?

--- Comment #2 from Tomáš Chvátal tchvatal@suse.com --- Happens with 4.4.35 but not so often... This time I had to actually stress the machine by playing video (even then I don't consider watching fullhd movie to be so rough on the usage).

--- Comment #7 from Tomáš Chvátal tchvatal@suse.com --- I am reopening this because I discovered that if install thermald and enable the service on the laptop the MCE eerors disappear. Probably the termald sorts out the throttling and other issues.
I would say we should enable this service by default on new cpus and probably install it in laptop pattern.
Adding michal to cc per his request :)

--- Comment #8 from Takashi Iwai tiwai@suse.com --- We can add supplements to thermald specifying the CPU IDs that require thermald, too, instead. Adding thermald maintainters to Cc.
BTW, does this happen also with SLE12-SP2 kernel?

Yes for the old kernel; I tried leap first... :)
Technically if we have way how to identify CPU then I am fine for it being supplements. But we also need to change default presets for systemd to enable thermald by default if installed.

Oh, then it's a problem since I'm not sure whether thermald is included in SLE[SD]12-SP2. Thomas?

That's true. Let's leave the decision to thermald maintainers.

It is not present on the SLES12 atm, only Leap and TW.

@thermlad-maints: so what is your take, would you guys add those supplements?

--- Comment #15 from Brice DEKANY brice.dekany@suse.com --- Hi,
Looks like lack of thermald by default on intel modern CPU makes SUSE distro less perfomant

--- Comment #16 from Takashi Iwai tiwai@suse.com --- This seems to be completely forgotten / overlooked.
Fabian, Thomas, would you mind adding Supplements? e.g. either modalias cpu or PCI for boards.

--- Comment #17 from Fabian Vogt fvogt@suse.com --- I vaguely remember some report(s) about thermald actually causing the device to overheat and do a hard shutdown. That's not too unlikely, considering its main purpose is to avoid throttling the CPU harder than necessary when the thermal limit is approached/reached.
The thermal limit shouldn't be reached under normal circumstances (like "browsing+ssh" in the original comment), and so thermald shouldn't be absolutely necessary with a properly designed cooling solution. Unfortunately many laptops do not have one, so thermald has a noticable impact on performance on those. However, that comes at a cost: The device will run hotter.
Any opinions about this?
Supplements: (modalias(cpu:type%3Ax86*ven0000*) if kernel)
While there are more specific modaliases which could be used here (like some intel specific ACPI platform devices), those may change in the future and then the supplements would silently not work anymore.
Ideally it only matches physical hardware, but I don't think we have any capability for that (yet).

Yes. It's good to give users a choice :)

I guess this would work as a first shot, that's similar to ucode-intel.
While there are more specific modaliases which could be used here (like some intel specific ACPI platform devices), those may change in the future and then the supplements would silently not work anymore.
Agreed.
Ideally it only matches physical hardware, but I don't think we have any capability for that (yet).
And, thermald won't be enabled / activated by the package installation alone, right?

--- Comment #19 from Thomas Renninger trenn@suse.com --- Sorry to highjack this one with another issue: I have this bug lingering around for quite some time.
ucode-amd is recommended on Intel CPU systems https://bugzilla.suse.com/show_bug.cgi?id=1158704
From Kernel:HEAD kernel-firmware: %package -n ucode-amd ... # new style (after 3.12 kernel somewhen) Supplements: modalias(cpu:type%%3Ax86*ven0002*) # old style (before 3.16 kernel) Supplements: modalias(x86cpu:vendor%%3A0002%%3Afamily%%3A*%%3Amodel%%3A*%%3Afeature%%3A*)
any ideas or seeing something obvious ;)

The Supplements is fine, but it's pulled just because of Recommends in the patterns-base-enhanced_base (as already suggested in bug 1158704). You may reassign the bug to Component patterns if it's really superfluous.
