Title:
  kernel-lts-wily crash running qemu KVM with OVMF

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  linux-image-generic-lts-wily/trusty-updates,trusty-security,now 4.2.0.19.14 amd64 [installed]
  qemu-system-x86/trusty-updates,trusty-security,now 2.0.0+dfsg-2ubuntu1.21 amd64 [installed]
  ovmf/trusty,now 0~20131112.2590861a-2 all [installed]

  Running

  qemu-system-x86_64 -enable-kvm -bios /usr/share/qemu/OVMF.fd

  under kernel 4.2.0 reliably crashes system. The same qemu command
  works normally using default 3.13 kernel.
