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. -- Sérgio M.
