Yes, Here is another QEMU bug found by FreeBSD :427ef2ee-6871-0d27-f485-90ad142f6266@kaod.org/">https://lore.kernel.org/qemu-devel/427ef2ee-6871-0d27-f485-90ad142f6266@kaod.org/
It would be interesting to boot directly the PowerNV machine from a FreeBSB kernel and a minimum inirtd without using the skiroot images and an iso. Are images available ? Thanks. C.
