Created attachment 97330
  --> https://bugs.freedesktop.org/attachment.cgi?id=97330&action=edit
dmesg from a 3.15 rc1

I have tried all the next kernels and even the one that comes by default in
14.04
but all leave to blank screen 

I have added the debug mode for intel drm and here is the dmesg from a 3.15 rc1
kernel (with the same behavior)
