qemu-system-x86_64 -display none -accel kvm -smp 2 -M q35 \
	-bios Build/OvmfX64/DEBUG_GCC5/FV/OVMF.fd \
	-chardev stdio,id=fw -device isa-debugcon,iobase=0x402,chardev=fw

Last log lines are ...

	AP Loop Mode is 1
	AP Vector: non-16-bit = 7EA7000/447
	WakeupBufferStart = 9F000, WakeupBufferSize = 1000
	AP Vector: 16-bit = 9F000/39, ExchangeInfo = 9F039/A4
	CpuMpPei: 5-Level Paging = 0

... and here it hangs.

Using OvmfPkgX64.dsc here.  Tried using Ia32 instead, hangs too,
at the same place.

take care,
  Gerd
