nvidia-367.57 with kernel 4.4.0-51-generic won't boot

[PlantDaddy]

Pretty much identical to bug 1642400 and bug 1638990 except that this behavior also happens with the most recent Xenial kernel, 4.4.0-51-generic.

If I boot into recovery mode on 4.4.0-51-generic, mount the filesystem as read/write, start networking, the resume normal boot, I can finally get into my window manager. But if I reboot and let
GRUB handle boot normally, it doesn't even let me enter my encryption passphrase. Just sits at a blinking cursor.

Switching back to nouveau works, but after reinstalling 367.57, the behavior returns and the aforementioned steps have to be followed.

Holding shift doesn't affect the outcome.

I expect that I should be able to boot normally with nvidia drivers, without any special steps to boot. But instead, I just get a blinking cursor before I can even unlock my encrypted drive.

Status changed to 'Confirmed' because the bug affects multiple users.

There is a fix. Press and hold 'Shift' while booting. It should bring up the login screen. You won't need to do this every single time, just once after failing to boot.

[PlantDaddy (plantdaddy)]

Is there a specific time in boot I should be holding shift? I have tried holding as soon as I start seeing POST messaging, and also tried once the GRUB menu came up.

But it still doesn't get me to the screen to enter my disk encryption password.
