[Bug 1571798] Re: Broadwell ECRC Support missing in Ubuntu


Attached are the requested logs from the system with the current issue.
I was not able to run apport due to our proxy.

The card in question is current at PCI Root Path 80:02.0 (Intel Quick
Assist 8950).

When running the command "setpci -s 80:02.0 160.w", the value returned
is "0000:80:02.0 @160 = 01e0", but the expectation is that it will be
"0000:80:02.0 @160 = 00a0", with the BIOS version we are running.

The issue also appeared on the 16.04 beta release that I tried.

  Broadwell ECRC Support missing in Ubuntu

Status in linux package 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.
