Title:
  Kernel Panic on Surface Pro

Status in linux package in Ubuntu:
  Expired

Bug description:
  I am using Ubuntu 15.04 on a Surface Pro (1st gen), dual-boting with Windows 8.1 and the linux kernel 3.19 is causing a kernel panic. The last kernel working was 3.16.0-38.
  I couldn't get any stack-trace (maybe apport has one), since my computer froze and i was on the desktop and wasn't on tty.
  The only way I could reproduce is to boot up Ubuntu then open up an application for example Software Updater. After a couple seconds, about like 10, the computer freezes, and a kernel panic happens. I can reproduce both in TTY and on the unity desktop.
  The issue report was made using the 3.16.0-38 kernel, which may have changed some values in the Apport debug information.
