Comment 33 for bug 761830

I had(have) the same issue.

This is an easy fix by editing /etc/grub.d/10_linux

changing:

     GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT vt.handoff=7"

to

     GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT"

Be sure to run "sudo update-grub2" after making the the changes to 10_linux. Boots straight to the prompt there after.

Hope this helps.
