I built a test kernel with the patch. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1571798 This test kernel needs both the linux-image and linux-image-extra .deb packages. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1571798 Title: Broadwell ECRC Support missing in Ubuntu Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Status in linux source package in Yakkety: In Progress Status in linux source package in Zesty: In Progress 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.
