Title:
  qemu-kvm -m bigger 4096 aborts with 'Bad ram offset'

Status in QEMU:
  Expired

Bug description:
  When I try to start a virtual machine (x86_64 guest on a x86_64 host
  that has 32GB memory, using kvm_amd module, both host and guest
  running linux-2.6.39 kernels) with "qemu-system-x86_64 -cpu host -smp
  2 -m 4096 ...", shortly after the guest kernel starts, qemu aborts
  with a message "Bad ram offset 11811c000".

  With e.g. "-m 3500" (or lower), the virtual machine runs fine.

  I experience this both using qemu-kvm 0.14.1 and a recent version from git
  commit 525e3df73e40290e95743d4c8f8b64d8d9cbe021
