Title:
  Null pointer dereference in mmu_set_spte.isra on 3.8.0-33-generic

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Dear all,

  We faced a kernel oops on KVM from a null pointer derefence on one of
  our hypervisors (running several KVM VMs). This led us to a serie of
  kernel oops affecting all the VMs and finally, the host crash. We
  couldn't really establish where from the first oops was comming (in
  order to reproduce the crash).

  You'll find attach the extract of syslog where you have the really
  first oops, and all the followings.

  We're using Ubuntu 12.04LTS. We're using latest releases available on
  it, including for KVM. We're using kernel 3.8 due to hardware
  constraints. And we're using kernel 3.8.0-33-generic due to
  regressions in newer kernels (not yet reported).
