Public bug reported:
My laptop updated its kernel today from 7.0.0-34-Generic to
7.0.0-38-Generic. First time booting after update, I go to the GRUB menu
and select Ubuntu. My screen went black. It was supposed to go to the
password screen to unlock my hard drive. My laptop will boot after
either going back to the 7.0.0-34-Generic kernel, or booting with
"nomodeset" option.
