dmesg output and error file

I have a black screen on booting.

I boot in recovery mode with option modeset=0, then I remove the module i915,
and reload it again with option modeset=1. then the screens turns black but I
still can send commands to the terminal. Sometimes it works well so I can go on
and start normally. 

The system is and HP pro 608 g1 tablet with and intel atom x5-z8500 and hd

System architecture: x86_64
Kernel: 4.8.0-rc1-hp+ (lastest drm-intel-nightly)
Linux Distribution: Debian Testing

I've attached dmesg output and /sys/class/drm/card0/error

Thanks Juan
