Thanks for testing, John.  To narrow it down further, can you test some
of the 3.18 release candidates?

They can all be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/

I'd suggest trying -rc1 first.  If that version does not have the bug,
try some of the newer candidates:

v3.18-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc1-utopic/
v3.18-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc4-vivid/
v3.18-rc7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc7-vivid/

Once we know the last good kernel version and the first bad one, we can
bisect between them.

Title:
  Broadwell ECRC Support missing in Ubuntu

Bug description:
  Here is the problem statement from the Dell team:

  When booting into Ubuntu 14.04.4 with a Broadwell CPU and an Intel
  Quick Assist Card, the memory location that corresponds to ECRC is set
  to 0x01e0, when the BIOS is setting this location 0x00a0 pre-OS boot.
  This causes the card to not function unless we implement the following
  workaround using setpci.

  “setpci –s AA:BB.C 160.w=0”, where AA:BB.C is the PCI Root Path for
  the Intel Quick Assit Card.

  We’ve verified the memory location is correct when booting to other
  OSes, such as RHEL 7.2 and Windows Server 2012 R2.

  If there is any information you can give as to why this may be
  occurring in Ubuntu or where we may start to debug when the memory is
  changed, we would appreciate it.
