I am having a really terrible experience with Fedora 20 KDE on Thinkpad 420i.

I installed Fedora 20 KDE on Thinkpad 420i, upgraded it to the latest and system freezes at the login screen. System temperature goes over limit either burning the system or shutting it down. Load average goes as high as 10. Fedora 20 is shipped with kernel 3.11.10 and I can confirm that I faced the problem on 3.13.8, 3.13.9 and 3.13.10 is a hit and miss.

I have filed a bug but it hasn't cracked a noise at Redhat Bugzilla. No response either from KDE Mailing list here and this is my last resort before I might have to forcibly switch to a more stable distro like Kubuntu (and that would be really sad).
