Maybe you should check your grub2 chkconfig whether it is OK, especially the "real_init" filed. Suggest if failed again, re-emerge dbus and systemd???

Hi, i've upgraded kernel from 3.12.13 to 3.12.20. I've make a oldconfig as usual, but with new kernel the boot blocks at the begining to the ramdisk loading. I've tried with other 3.12.2x with the same negative results. I use grub2 with systemd.
