[solved] kernel 3.1.5 kills suspend to ram

Hello all,

since the update to kernel 3.1.5 my system is not able to suspend to ram anymore. I haven't tested suspend to disk yet but I fear the result will be the same. System goes down but the wake up process hangs with a black screen. Only hard reset (!) can get me out here. Can't even change to another tty with ctrl-alt-Fx

Harvey

Edit: Same with suspend to disk. System doesn't even switch off. Both suspends were working before.

Do you have anything in kernel line?

What is your system/hardware (x86/x86-64, brand, CPU model, video card)?

No doubt but to do the magic ;-) we need information to isolate the problem. Usually, the problem with suspend-to-ram resides in the graphics card, but not always.

Have you tried to suspend/resume from the console without starting X? Have you tried to disable KMS? Have you tried to boot the kernel alone (something like init=/bin/sh) and suspend/resume (echo mem > /sys/power/state)?

If not, please try.

console: same effect
KMS: This is a nvidia card with the nvidia drivers. Do they even support KMS? If so, how can I disable this?
boot kernel alone: same effect

Meanwhile I tested kernel 3.1.5 with my intel-based laptop without problems. I have an older one with nvidia graphics which I will test later. But my desktop isn't willing to suspend anymore sad

Re: [solved] kernel 3.1.5 kills suspend to ram

You can also try to downgrade the linux package to discard other problems (recently the pm-utils was updated too).

If you don't know how, take a look to:
https://wiki.archlinux.org/index.php/Do … ckages#ARM

And get the package from:
http://arm.konnichi.com/core/os/x86_64/ … pkg.tar.xz

If it works with 3.1.4 you can upgrade again and look other alternatives to find the problem, if not, take a look to pm-utils quirks.

As I said before, I did this already and just linux 3.1.5 -> linux 3.1.4 is needed for suspend to work again.

Meanwhile I have tested another laptop with nvidia graphics and an older Intel Processor. This machine is working too sad
The problem seems to be specific to my desktop system. Not sure what else I can do to hunt this down.

My system could suspend to ram, but couldn't wake up(black screen).

Re: [solved] kernel 3.1.5 kills suspend to ram

I don't know what else to try to isolate the problem. Not taking into account the NVidia graphics, as you said it works, the common thing seems to be the processor family. You can check the changelog [1] in order to find what changed about your specific system.

Thank you for your reply.
I have read through the log, but I cannot find out the problem since I'm not a programmer, not good at English.
Howerver I found a commit about suspend:

commit b5e0fb085f337c2ab00532d09056da3525f2e847
Author: Kevin Hilman
Date:   Tue Nov 22 17:18:24 2011 -0800

    usb: musb: PM: fix context save/restore in suspend/resume path
   
    commit 5d193ce8f1fa7c67c7fd7be2c03ef31eed344a4f upstream.
   
    Currently the driver tries to save context in the suspend path, but
    will cause an abort if the device is already runtime suspended.  This
    happens, for example, if MUSB loaded/compiled-in, in host mode, but no
    USB devices are attached.  MUSB will be runtime suspended, but then
    attempting a system suspend will crash due to the context save
    being attempted while the device is disabled.
   
    On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be
    called late in the suspend path (by the PM domain layer) if the driver
    is not already runtime suspended, ensuring a full shutdown.
   
    Therefore, the context save is not needed in the ->suspend() method
    since it will be called in the ->runtime_suspend() method anyways
    (similarily for resume.)
   
    NOTE: this leaves the suspend/resume methods basically empty (with
          some FIXMEs and comments, but I'll leave it to the maintainers
          to decide whether to remove them.

I don't know whether this is related to the problem or not.

Re: [solved] kernel 3.1.5 kills suspend to ram

You could compare your systems (hardware and modules) to know what they have in common and thus approach the problem.

Also, please, join the bug reports and fix their description to something more relevant like "Resume from suspend-to-ram broken in kernel 3.1.5" (just a suggestion).

Thank you for your reply.
I have just reported on Bugtracker too.
I don't use encryption at all(...dangerous!), so perhaps it is not related, but I'm not sure.

I hope someone will solve this issue...

Re: [solved] kernel 3.1.5 kills suspend to ram

This seems to be a problem with Redhat too:
https://bugzilla.redhat.com/show_bug.cg … &id=768010

I think this is an upstream bug in the kernel.

Re: [solved] kernel 3.1.5 kills suspend to ram

YAY! I found it! My system suspends again. smile

Here is what I did: My system's BIOS has in 'Power Management Setup' an option 'HPET support' (high precision timer support) which can be set 32bit, 64bit or disabled. If disabled, the suspend works with kernel 3.1.5. Maybe the kernel cracks can guess now where all the trouble comes from. For me it's working and that is all I need wink

Nevertheless this seems to be only a workaround so I won't mark the thread as SOLVED.

Re: [solved] kernel 3.1.5 kills suspend to ram

Thanks Harvey, your workaround works fine with my system. Not having a BIOS that allows me to disable HPET, I had to disable it by adding hpet=disable to the kernel parameters.

Re: [solved] kernel 3.1.5 kills suspend to ram

I just found this thread after experiencing the same issue; for me, disabling HPET in grub's menu.lst works (thanks for the workaround!), but I'm running kernel 3.1.8-1, so either the underlying issue wasn't completely fixed, or they broke it again going from 3.1.7 to 3.1.8, or something else...any ideas? (I'm very happy to have a workaround, but it'd be nice to have it just working!)

That's bad news. My systems suspends without problems with kernel 3.1.8. Is your system completely freezed after suspend? Are there any error messages?

It seems to wake up just fine (fans turn on, hard drives spin up, etc.), except that the screen doesn't turn on (and no amount of moving the mouse or keyboard changes that). To top it off, I can SSH in from my laptop, so the only thing wrong seems to be the screen.

Looking in /var/log/pm-suspend.log I don't see any obvious errors; is there anywhere else I should check for errors?

It seems to wake up just fine (fans turn on, hard drives spin up, etc.), except that the screen doesn't turn on (and no amount of moving the mouse or keyboard changes that). To top it off, I can SSH in from my laptop, so the only thing wrong seems to be the screen.

This sounds like an unrelated issue. Your graphics card is not waking up again. The former bug caused the whole system to freeze. Have a look a /var/log/Xorg.0.log. What card do you have? What driver do you use? Try from a ssh shell

init 3

and then

init 5

Does this resurrect the card?

Re: [solved] kernel 3.1.5 kills suspend to ram

Well, whatever happened doesn't seem to be reproducible! I'm sorry for muddying the waters here with an issue unrelated to the original one. smile I removed the hpet=disable line from /boot/grub/menu.lst and rebooted, then once my system had finished booting I suspended it...and when I woke it, it woke back up just fine. I've tried it a couple of times now, and no issues. I guess it was something transient, and I apologize for the bother!
