Public bug reported: Hello,
Since updating to linux 3.8-rc3 my CPU is clearly overheating compared to linux 3.7. kernel Idle Busy (VLC playing, Chromium open with several tabs) 3.7 46°C 51°C 3.8-rc3 54° 61°C Diff +8°C +10°C There is no problem with CPU load, in both case it stay around the same percentage. NB: I wanted to use ubuntu-bug to report this bug but for some reason it thinks my linux kernel come from mainline when it comes from the ubuntu repositories. So, if I need to complete this bug report with logs, please inform me.
