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. ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Vivid) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Yakkety) Importance: High Assignee: Joseph Salisbury (jsalisbury) Status: Confirmed ** Also affects: linux (Ubuntu Wily) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Vivid) Status: New => In Progress ** Changed in: linux (Ubuntu Wily) Status: New => In Progress ** Changed in: linux (Ubuntu Xenial) Status: New => In Progress ** Changed in: linux (Ubuntu Yakkety) Status: Confirmed => In Progress ** Changed in: linux (Ubuntu Xenial) Importance: Undecided => High ** Changed in: linux (Ubuntu Wily) Importance: Undecided => High ** Changed in: linux (Ubuntu Vivid) Importance: Undecided => High ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Wily) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Vivid) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) -- 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 Vivid: In Progress Status in linux source package in Wily: In Progress Status in linux source package in Xenial: In Progress Status in linux source package in Yakkety: 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.
