Sorry for the unnecessary misleading.
In my case, hanging out after sleep is related to - mq-deadline/ext4 IO hangs.

I have no idea why he disappeared default CFQ scheduler, though in the
configuration it is:
CONFIG_IOSCHED_CFQ=y
CONFIG_DEFAULT_CFQ=y
CONFIG_DEFAULT_IOSCHED="cfq"

4.12.3
cat /sys/block/sda/queue/scheduler
[cfq]

4.13-rc2
cat /sys/block/sda/queue/scheduler
[mq-deadline] bfq none

After
echo none > /sys/block/sda/queue/scheduler
I did not noticed any hang on the kernel 4.13-rc2 (out after sleep).
