[Bug 1647075] Re: Unable to enter password to decrypt filesystem on boot after upgrading kernel to 4.4.0-51

 

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  Unable to enter password to decrypt filesystem on boot after upgrading
  kernel to 4.4.0-51

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Xenial:
  Incomplete

Bug description:
  Disk is encrypted using full disk encryption.  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?
