[Bug 1500751] Re: Cryptsetup Keyboard not working on Xubuntu 3.19.0-30

[Morten Clausen]

I can confirm that 3.19.0-31-generic #36~RevertsV2 works without any of
the issues.

@rolfinator (seb2): Yes I have the same issues with the 3.19.0-30 kernel
stated in the initial post (plus some random system freezes, except the
workaround "boot -> wait for dm-crypt passphrase, which can't be entered
--> reboot --> enter passphrase" works on 3.19.0-30, but system freezes
remain afterwards).

Title:
  Cryptsetup Keyboard not working on Xubuntu 3.19.0-30

Status in cryptsetup package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  In Progress

Bug description:
  I am running Xubuntu 15.04 and just upgraded to the latest kernel (3.19.0-30).
  After upgrading the boot time is longer (what is negligible) but the more severe error is, that I cannot enter my passphrase when I see the crypt dialog.
  I just see the dialog to enter my passphrase, but when I try to enter it, nothing appears in the textfield. I tried with the builtin laptop keyboard but also with an external USB keyboard.

  I thought about supplying more information, but things like the syslog
  are not helping apparently (I was not able to boot until the syslog
  would capture information...). If you need anything I can provide, I
  gladly help.

  [Test case]
  1. On an affected system boot into kernel 3.19.0-30

  [Solution]
  The "solution" for now is booting the older Kernel 3.19.0-28 (which isn't a real solution).
