I was able to reproduce this bug. The panic not only happens at install time, but also if you install the affected kernel on an already installed system.
I'm in the process of bisecting the issue now. The bug also exists in upstream 4.2 final. * Panic happens with latest Vivid kernel(3.19.0-28) * Does not happen with 3.19.0-15 * Does not happen with upstream 3.19.8-ckt6 * Panic happens with upstream 4.2. I'll update the bug with my progress. ** Changed in: linux (Ubuntu Wily) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Wily) Status: Confirmed => In Progress ** Also affects: linux (Ubuntu Vivid) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Vivid) Status: New => In Progress ** Changed in: linux (Ubuntu Vivid) Importance: Undecided => High ** 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/1495983 Title: [Hyper-V] kernel panic occurs when installing Ubuntu Server 15.10 x32 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1495983/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
