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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571798 Title: Broadwell ECRC Support missing in Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1571798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
