[Bug 1546294] [NEW] keyboard doesn't work in initrd for 4.4.0-5.20

 

Public bug reported:

When booting kernel 4.4.0-5.20, the keyboard doesn't work during boot,
so I can't input the disk encryption key.

This works fine with earlier kernels (for example linux-
image-4.2.0-29-generic, which is also installed on the same machine).
