Ok,

Fedora 19 has caused nothing but problems;

I have a desktop with an AMD 7750 Graphics card which since upgrade fails to load gnome at all, tried akmod kmod, direct drivers nothing ... (there's a separate question here I'm following on this issue).

But the focus of this question is infact an i5 laptop, which never having had a problem with 18, since upgrading is constantly throttling the cpu:

[26670.911219] CPU1: Core temperature above threshold, cpu clock throttled (total events = 1)
[26670.911221] CPU0: Core temperature above threshold, cpu clock throttled (total events = 1)
[26670.911222] CPU2: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.911223] CPU3: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.911224] CPU0: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.911232] CPU1: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.912202] CPU1: Core temperature/speed normal
[26670.912204] CPU2: Package temperature/speed normal
[26670.912204] CPU3: Package temperature/speed normal
[26670.912209] CPU0: Core temperature/speed normal
[26670.912209] CPU1: Package temperature/speed normal
[26670.912212] CPU0: Package temperature/speed normal

The cpu in question: Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz

Even stranger is on inpsection of /proc/cpuinfo the 4 notes cores are all running at differnt cpu Mhz ...

cat /proc/cpuinfo | grep MHz
cpu MHz     : 1800.000
cpu MHz     : 1025.000
cpu MHz     : 1475.000
cpu MHz     : 2350.000
cat /proc/cpuinfo | grep MHz
cpu MHz     : 1825.000
cpu MHz     : 2600.000
cpu MHz     : 3025.000
cpu MHz     : 2825.000

Seems to me that the CPU scaling is miss behaving; any suggestions as to a remedy?

Question edited. Please un-check the @blackjack 's answer if complete Fedora re-installation didn't fix the problem / you don't consider it a valid answer.

Recent kernel updates appear to have alleviated the issue.

Looks like the problem is back again with the latest 4.6.4.201.fc23.x86_64. I am using Lenovo G780 and I got this in system logos:

 Jul 27 19:47:57 w0rkstation kernel: CPU0: Package temperature above threshold, cpu clock throttled (total events = 9)
Jul 27 19:47:57 w0rkstation kernel: CPU1: Package temperature above threshold, cpu clock throttled (total events = 9)
Jul 27 19:47:57 w0rkstation kernel: CPU3: Package temperature above threshold, cpu clock throttled (total events = 9)
Jul 27 19:47:57 w0rkstation kernel: CPU2: Package temperature above threshold, cpu clock throttled (total events = 9)
Jul 27 19:47:56 w0rkstation kernel: CPU1: Core temperature above threshold, cpu clock throttled (total events = 1)
Jul 27 19:47:56 w0rkstation kernel: CPU0: Core temperature above threshold, cpu clock throttled (total events = 1)

One of the cores is always 100% busy even if nothing heavy is running on. Some time its core 1 some time its core 4. After switching back to 4.5.7-202 everything looks normal so far.

(Linux w0rkstation 4.5.7-202.fc23.x86_64 #1 SMP Tue Jun 28 18:22:51 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Wed Jul 27 21:16:24 EEST 2016)

I would suggest you reporting a bug on bugzilla.redhat.com against kernel. It is not advised to post your problem as an answer to a question that was asked three years ago. Rather open a new question.

I got cpu_freq errors on my Intel(R) Core(TM) i5, with kernel 4.6.4-201.fc23.x86_64 , and my computer have 4 years of fedora kernels installed , so seem kernel 4.6.4 issue, looking at bugzilla find find a solution ...

Same issue for several days on two different computers. Did a complete backup of "home" directory and did a new install using the Fedora 19 live dvd. After install, which was fast and successful, copied files back to home directory.
