Title:
  invalid opcode: 0000 [#1] SMP - kernel BUG at inode.c

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Description:	Ubuntu 14.04.3 LTS
  Release:	14.04
  linux-image-3.16.0-50-generic:
    Installed: 3.16.0-50.67~14.04.1

  At or during accessing the filesystem on an external USB drive, the kernel bug (see below) occured.
  Afterwards, an "ls" did not react, i.e. hangs until closing the terminal.
  The drive itself seems to be ok, since it passes a SMART check.
  The filesystem was created by using the standard Ubuntu 14.04 encryption mechanism (LUKS).
