Bootloop OOS 3.0.2 / Boeffla 2.1 Beta 1 / SuperSU 2.74

Hi,

So i've been running OOS 3.0.2 Boeffla 2.0 and Super Su 2.74 without issues.
This morning I tried to flash Boeffla 2.1 Beta 1.
I followed steps from http://boeffla-kernel.de/index.php/6...ernels-new-app as prescribed by @Lord Boeffla

flash rom flash kernel flash supersu (if required by your rom) let it boot enjoy

Unfortunately, the device stays on the OOS boot animation for ever.
The minute I flash back the stable kernel all is good in the world.

Any ideas on what could be causing the issue ?

Thanks
