Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4 stable kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

I could enter my password to decrypt the disk when booting in 4.4.0-47, but after upgrading to 4.4.0-51, I'm prompted for the password, but I can't type anything. I think the last time this happened there was some change with the USB HID modules or something (I'm using a USB keyboard). Has there been any changes to the USB modules or configuration between kernel 4.4.0-47 and 4.4.0-51?
