If with "grub banner" you mean the menu from which you select the OS and kernel to boot then that is different from the "log on screen", which is the Display Manager (DM): GDM for GNOME, KDM for KDE, etc, etc. Depending on what bootloader you use, GRUB legacy or GRUB2, and how it was configured you may see (or not see) kernels versions displayed at the "grub banner". If you don't see any entries try pressing the "e" key (edit) or ESC on bootup after your BIOS diagnostics finished (if it shows at all). If you now can select an entry try picking the previous kernel. If only the 3.6.6 kernel line shows then select that, press "e", move the cursor to the kernel line, press "e" again, move the cursor to the end of the line, add a space and then (w/o quotes) "systemd.unit=rescue.target". Now press enter and then "b" to boot into single user level where you can log in on the command line. Best first check /var/log/messages and other log files in /var/log for clues.

No idea where exactly but you'll likely find such options in /etc/sysconfig or /etc/system*/.

It sure is an inconvenience to have a non-booting system but
setting the option to "off" does not fix things.
IMHO it would be better to configure GRUB(2) to show you earlier kernels to boot so you can check lo files and run diagnostics to
fix things the right way.
