Thanks for replying , I had verified all files , done a full prelink
-avmR ,  I followed some tips on
https://fedoraproject.org/wiki/Common_F20_bugs especially:

3.1 System fails to boot after install using LVM Thin Provisioning

I even try 4.10 suggestions, I changed my disk partitions from MBR to
MPT (works better). In meanwhile also fixed "CUPS hangs on shutdown" 

And all options doesn't *worked*, when I almost give up, for today,
occasionally I removed
"systemd.log_level=debug" from kernel boot parameters 
and guess what, it boot cleanly , 
systemd.log_level=debug prevents my system to boot ! 

Conclusion: 
GRUB_CMDLINE_LINUX="quiet systemd.log_level=debug" doesn't boot 
GRUB_CMDLINE_LINUX="systemd.log_level=debug" doesn't boot  
GRUB_CMDLINE_LINUX="debug systemd.log_level=debug" boots
GRUB_CMDLINE_LINUX="quiet" boots
GRUB_CMDLINE_LINUX="" boots 

I even think fedup problems was consequence that I had forget
systemd.log_level=debug in default GRUB_CMDLINE_LINUX 

Hope that could help something, bye.
