Bug 1282785

Description of problem:

I have a Rawhide system with encrypted disk which doesn't unlock if the latest kernel is used but boots fine otherwise. 


Version-Release number of selected component (if applicable):
kernel-4.4.0-0.rc0.git9.1.fc24.x86_64

How reproducible:
Always (?)

Steps to Reproduce:
1. I have sda2 and sda3 encrypted (for LVM and swap), password contains only ASCII characters. 
2. While booting with kernel-4.4.0-0.rc0.git9.1.fc24.x86_64 I'm asked for the password but the disk isn't unlocked.
3.

Actual results:
System fails to boot

Expected results:
System boots fine

Additional info:
With kernel-4.4.0-0.rc0.git6.1.fc24.x86_64 I'm presented with a text prompt to enter the disk password. Disk is unlocked and system boots fine.

With kernel-4.4.0-0.rc0.git9.1.fc24.x86_64 I'm presented with a graphical prompt to enter the password (!!! this is difference in behavior) and the disk isn't unlocked.

The latest kernel is missing the initrd16 line but the initrd.img appears to be there.

I've recently (yesterday) updated the system but I have no idea how I ended up with this configuration.
