Hello all,
I'm seeing this crash trying to boot a KVM virtual machine. This kernel
was compiled with pseries_le_defconfig and run using the following qemu
commandline:
qemu-system-ppc64 -enable-kvm -cpu POWER8 -smp 4 -m 4G -M pseries
-nographic -vga none -drive file=vm.raw,if=virtio,format=raw -drive
file=mkvmconf2xeO,if=virtio,format=raw -netdev type=user,id=net0
-device virtio-net-pci,netdev=net0 -kernel vmlinux_tscr -append
'root=/dev/vdb1 rw cloud-init=disabled'
qemu-system-ppc64 --version
