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
