Sorry, above I meant "virtio-blk freeze" (no virtio_rng). But in any
case it's obviously not directly related to this bug, so disregard it...
Sorry for the noise.

After some research, the problem is that mpc8544ds has only 2 PCI slots
defined (hw/ppc/mpc8544ds.c -> pmc->pci_nr_slots = 2;). This in turn
results in DTB only contain 2 devices in pci@e0008000/interrupt-map. Too
bad qemu doesn't complain when more devices are added - the PCI bars
seem to be OK,
Not even reverting the patch worked for me, and it's still broken on
qemu 5.1.
For example:
~/OSS/qemu/ppc-softmmu/qemu-system-ppc -machine mpc8544ds -nographic
-cpu e500mc -serial mon:stdio -kernel zImage -initrd rootfs.ird -append
'console=ttyS0,115200' -device e1000,netdev=main -netdev
Public bug reported:
This is tested using qemu 2.4.1, but it looks like the code
qemu/hw/ppc/e500.c has not changed since. This looks like the source of
the problem:
