Is it a Intel+Nvidia hybrid? If so, does it happen even with
CONFIG_VGA_SWITCHEROO=n?

For what it's worth, I have a the X240's bigger brother --- a T540p
(with intel graphics and the 3k panel) running 3.14-rc2, and
suspend-to-ram is working without any problems on my laptop.

It's not Intel+Nvidia. It's Intel Core i7-4600U 2.1 GHz, Intel HD Graphics 4400.

I checked my config. CONFIG_VGA_SWITCHEROO is not set.

Interesting. Perhaps it's the USB options. I had these set to "y"

CONFIG_USB_XHCI_HCD=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_EHCI_ROOT_HUB_TT=y
CONFIG_USB_EHCI_TT_NEWSCHED=y
CONFIG_USB_EHCI_PCI=y

Again, These same config works find on X230. It's very strange. The
same hard disk (SSD) can suspend-to-ram on the X230 but not on the
X240. The X230 has i7-3520M vs X240 i7-4600U.

I've even tried with all the USB set to "n" and still couldn't S2D.
May be the graphic?

Thanks,
Jeff

OK. Then it's a different thing as I expected.

The other possible change in hda_intel.c is the enablement of runtime
PM for Panther Point. But it's been working for other chips, so
wondering why it hits anything. In anyway, please give the full
Oops messages not only the stack trace.

Any difference in the sound hardware, i.e. PCI controller and codec
chips?

Do you mean S2R? I thought the bug is about S3?

# X230 reported the sound card as:
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset
Family High Definition Audio Controller (rev 04)
== HDA Intel PCH, ALC269VC Analog

# X240 reported the sound card as:
00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio
Controller (rev 04)
== HDA Intel PCH, ALC292 Analog

Now I managed to make suspend-to-ram work by using sound as module
instead of build-in.

Here's the difference ...

# bad
CONFIG_SND_HDA_CODEC_HDMI =y
CONFIG_SND_HDA_INTEL=y
CONFIG_SND_HDA_INPUT_BEEP=y
CONFIG_SND_HDA_CODEC_HDMI=y
CONFIG_SND_HDA_GENERIC=y

# good
CONFIG_SND_HDA_CODEC_HDMI =m
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_INPUT_BEEP=m
CONFIG_SND_HDA_CODEC_HDMI=m
CONFIG_SND_HDA_GENERIC=m

Strange?

Of those modules, which are loaded? If you load all of them and then
try to suspend, does it still work?

It might be the remaining bugs of modularization in 3.14-rc2.
A few patches are found in for-linus branch of sound git tree, which
are included in Today's pull request. Could you give it a try?

Pulled, but still the same. Modularized works fine -- even the modules
remains, s2r works. But setting to "Yes" ... won't suspend. I don't
kow how to capture those errors above the screens :(

Any suggestion on how to debug this? bisect? Ted, does your T540p work
with CONFIG_SND_HDA_INTEL=y instead of "m" ?

I can give this a try on my next kernel rebuild.

BTW, I am noticing some other suspend-to-ram wierdnesses. In
particular, in about 1 in 10 to 1 in 20 suspend, the led lights on the
ethernet port are stuck on after the suspend, which I suspect means
we're not shutting down the peripherals all the way, and thus wasting
battery while the laptop is suspended.

Also, I am using a password to secure my HDD, and in most cases, the
HDD is left powered on so I can still access the HDD. However, about
10% of the time, the HDD seems to get completely powered down, such
that it needs to have the password sent again to unlock the drive.
Since I am using the BIOS to send the password to the HDD, it means I
have to force a reboot in order to regain access to the drive.

So this is either a S2R bug in that we're not powering down the HDD
sufficiently to maximize power savings most of the time, or that we
need to be able to reauthenticate the HDD to unlock it after a
suspend/resume cycle --- something which it sounds like Linux doesn't
support all that well. (I only recently started using HDD/SSD
passwords because I now have devices with FDE, and I've been trying to
secure my computing environment as much as possible.)

I can confirm that suspend-to-ram hangs on my T540p if I build with
CONFIG_SND_HDA_INTEL=y. I ran the test using v3.14-rc3.

I checked CONFIG_SND_HDA_INTEL=y on my HP laptop with Haswell, but it
worked fine. Could you give config?

I don't have that config any more. But I started with my the 3.14-rc3
config, turned off changed CONFIG_SND_HDA_INTEL to be =y, and then ran
"make oldconfig ; make deb-pkg". See attached....
