Be aware that improper usage of kernel features can cause serious damage to your device!

Only use the stuff above if you know what you're doing!

In agreement with the GPL, you can find the sources and defconfig used to compile this kernel right here.

Known Issues:

Please keep in mind that CM12.1 sources are still work in progress. As a result, some features may be broken or only partially working.

That's why I decided to only list device-specific issues below.

Below ~60% battery, the displayed battery level will reduce significantly on rebooting. This is a known issue with all AOSP based ROMs.

After switching to a new battery, I noticed this behavior is related to automatic battery calibration and directly affected by the health of your phone's battery.
