I tried to reproduce this failure, but I failed. I compiled linux-next branch source code of linux-pm.git with this config, then I used qemu to boot a guest with my compiled kernel, it worked well.
QEMU command line is: ./x86_64-softmmu/qemu-system-x86_64 -hda /home/fedora21.img \ -kernel /home/linux-pm/arch/x86_64/boot/bzImage \ -m 512,slots=100,maxmem=100G -smp 2,maxcpus=100 -serial stdio -enable-kvm \ -initrd /home/initramfs-4.6.0-rc2-00250-g8767898.img -append "root=/dev/sda3 console=ttyS0
Anyone succeed?
Thanks, Zhu
