Title:
  Arm emulation do a crash

Status in QEMU:
  New

Bug description:
  Hello, I have try multiple image for the raspberry pi, with this cli:
  /usr/bin/qemu-system-arm -kernel kernel-rasptoo -M versatilepb -cpu arm11=
76 -hda hdd.img -m 256 -append "root=3D/dev/sda2 loglevel=3D7 debug" -seria=
l stdio -no-kvm
  I don't know why, with kvm it say:
  KVM not supported for this target
  No accelerator found!

  I can't debug it with gdb, it crash after the kernel boot (the qemu appli=
cation crash).
  I'm under gentoo:
