Hi all;
Daily I see anywhere from 10 - 50 or more of these alerts via abrt. I'm
running Fedora 23 (KDE Spin) fully up to date on a Lenovo X1 carbon 3rd gen.
In all the alerts I see that the trip temp was exceeded, and then dropped
below the trip temp within 1 second.
Below is a sample of the output.
Should I be concerned? If not can I disable the popup alert? If so,
recommendations? should I consider cleaning & replacing the cpu thermal
compound?
Thanks in advance
The kernel log indicates that hardware errors were detected.
System log may have more information.

I think any MCE event shoudn't be ignored. There's just no way to know
if it's bogus or not. I get these on my machine periodically to no ill
effect and there's an upstream kernel bug with no response for years.
I thought it should be true that the hardware itself won't allow an
overheat, either GPU or CPU, and yet these messages suggest otherwise.
What I've been doing is using thermald which you can get from copr.
https://copr.fedorainfracloud.org/coprs/hadrons123/thermald/
However, what I just realized is that it says that 1.5.3 version build
has failed, and yet rpm -q shows 1.5.3 is on my system. And 'thermald
--version' also shows it's 1.5.3 and it's running. But it doesn't seem
to be working or producing the same messages it used to, where it'd
throttle the CPU automatically. Hmmm any wonder why it's seems hotter
than usual. Crap!
Well it appears to be doing something still, if I relaunch it in debug
mode. I guess maybe the new build is just not as verbose as the
previous build, by default. What I still don't get is how the copr
build state is failed, and yet I have that same build installed.
Thanks for the feedback, I've installed thermald, added it to
/etc/rc.d/rc.local and so far have not seen a single cpu temp alert.
