Title:
  QEMU-SYSTEM-PPC64 Regression QEMU-4.0.0

Status in QEMU:
  New

Bug description:
  I have been using QEMU-SYSTEM-PPC64 v3.1.0 to run CentOS7 PPC emulated
  system. It stopped working when I upgraded to QEMU-4.0.0 . I
  downgraded back to QEMU-3.1.0 and it started working again. The
  problem is that my CentOS7 image will not boot up udner QEMU-4.0.0,
  but works fine under QEMU-3.1.0.

  I have an QCOW2 image available at
  https://www.mediafire.com/file/d8dda05ro85whn1/linux-
  centos7-ppc64.qcow2/file . NOTE: It is 15GB. Kind of large.

  I run it as follows:

     qemu-system-ppc64 \
        -name "CENTOS7-PPC64" \
        -cpu POWER7 -machine pseries \
        -m 4096 \
        -netdev bridge,id=netbr0,br=br0 \
        -device e1000,netdev=netbr0,mac=52:54:3c:13:21:33 \
        -hda "./linux-centos7-ppc64.qcow2" \
        -monitor stdio

  HOST: I am using Manjaro Linux on an Intel i7 machine with the QEMU
  packages installed via the package manager of the distribution.
