I will go back and retest the kernels you've posted. I'll start with
the last one I said was bad and verify that it was actually bad, then go

Broadwell ECRC Support missing in Ubuntu

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.
