Hardware: i7-4770 CPU, Asrock Z87 Pro3 Motherboard, no extra graphics, ethernet, audio card,

Suspend to RAM and wake up is normal.

Hibernate to disk and wake up is normal at the first time. When hibernate the second time,
the OS is booting, and, I can hear the movie sound from the waking OS, but, the display show
the message "No signal", and screen is black, the display LED become orange color, normal
work color is blue. Press any key is no effect.

I tried some video-quirks in /usr/lib/pm-utils/video-quirks, but no effect.

I tried add kenel boot parameters in grub.cfg: notsc, irqpoll. No effect.

Tried use uswsusp, no effect.

Tried debug pm-utils using the way:
echo reboot(or platform, shutdown) > /sys/power/disk
echo disk > /sys/power/state

No effect.

Tried test mode of hibernation using script below:
<code>
#!/bin/sh

item=""

case "$1" in
  1)
    item="freezer"
  ;;
  2)
    item="devices"
  ;;
  3)
    item="platform"
  ;;
  4)
    item="processors"
  ;;
  5)
    item="core"
  ;;
  6)
    item="none"
  ;;
esac

echo ${item} > /sys/power/pm_test
echo platform > /sys/power/disk
echo disk > /sys/power/state

exit 0
</code>

No any reflection in "freezer" mode;
"devices", "platform", "processors", "core" is working normally.
Twice test every mode.

"none" mode worked when first hibernate and wake, but failed at
the second hibernate and wake with the same symptom described top.

Hi,

Dear Pm-utils developers, I found a temporary method to resolve this
bug.

My motherboard Asrock Z87 Pro3 has three display ports:D-Sub, DVI-D and
HDMI. And my display AOC I2351Fe has two ports: D-Sub and DVI-D.

When plug only D-Sub(VGA) line between Motherboard and display, every
time resume from hibernate state will fail at display "no signal".

When plug only DVI-D line between Motherboard and display, every
first time resume from hibernate state will success, and the second
resume from hibernate will fail at display "no signal".

When plug both D-Sub and DVI-D lines between Motherboard and display,
every time resume from hibernate will success. I resolved this bug.

Another tips maybe helpful debug this bug for developers:

Plug both D-Sub and DVI-D lines, when set display "Auto" accept D-Sub or
DVI-D signal, resume from hibernate state, the first boot screen(Asrock
logo appear) inform "DVI-D" or "D-Sub" signal used; After Grub menu, in
the resuming screen(show N% resumed), inform "D-Sub" signal used;
Inform "DVI-D" signal used when unlock login window appear.

Plug both D-Sub and DVI-D lines, when set display only accept DVI-D
signal, resume from hibernate state, the first boot screen(Asrock logo
appear) inform "DVI-D" signal used; After Grub menu, inform "DVI-D, No
 Signal", the screen is black, can't see the resume progress; Inform
"DVI-D" signal used when unlock login window appear.

Although, I have resolved this question temporarily, but I don't know
if it is harmful for my hardware with connecting motherboard and
display using two lines above. And, I think maybe there are more and
more Linux users will meet this question(multiple display ports on
motherboard or display).

Hopeful my information is helpful for fixing this bug. If need more
detail information please tell me.
