Unresponsive harddrive unlock screen after kernel upgrader 4.4 -> 4.8
I have this strange error after upgrading my kernel from 4.4 to 4.8. I have an encrypted harddrive and the unlock screen only responds when I boot in 4.4. Whenever I choose 4.8 the unlock-screen is completely unresponsive.
It is not critical for me to move to 4.8, but I’d really like the better battery-performance gained by the upgrade.
Any suggestions as to how I can fix this? FYI, I installed the kernel with the following command:
sudo apt-get install linux-image-4.8.0-34-generic linux-headers-4.8.0-34 linux-headers-4.8.0-34-generic --fix-missing
