Suspend to RAM (sleep) goes to sleep but fails to wake.

[Arthur Peters]

The laptop is a Compaq Presario R3000z. With an AMD64 processor at 1.8GHz, 784MB
RAM, a GeForce4 440 Go 64MB graphics, Broadcom BCM4306 mini-PCI wireless, and
all the chitsets are nVidia nForce.

I have setup a wiki page about my breezy experiences on this laptop:
https://wiki.ubuntu.com/LaptopTestingTeam/CompaqPresarioR3000z

Suspend to RAM (sleep) goes to sleep but fails to wake. It starts to wake but
after a while the Caps-lock starts flashing which I beleave means that it
oopsed. This is true starting from X, starting from single-user mode, and
starting from single-user mode with most of the modules unloaded.

I could not capture the OOPS because it doesn't make it to disk. If there is a
way to get the OOPS I'd be willing to do it. I have a bunch of other machines so
serial console or ethernet console would be doable.

It does hibernate properly, except for USB which completely fails after restart.

I'm afraid that we'll need a serial console dump. In order to get one, you'll
need a patch to your kernel - are you happy to rebuild a kernel yourself?

Yes, but could you tell me what kernel source to start from?

Also do I simply need to turn on serial console? Or is there more?

Also can I build the kernel with simply make; make modules_install; ... Or do I
need to use make-kpkg for it to come out right? I'm not a fan of make-kpkg.

I'll get a null modem cable so I'm ready for this. ;-)

> PS: BTW, we're lucky thing has a serial port. Laptops are bad that way sometimes.

OH, NO. The laptop doesn't have a serial port. I misremembered. It has ethernet
(RTL8139), parallel, USB, etc.

I'm going to try to do it with netconsole over my ethernet LAN.

I'm going to build a kernel from the sources in the linux-source-2.6.12 package.
I will use the exact .config except for adding netconsole and building-in my
ethernet driver.

Wish me luck!

[Arthur Peters (amp)]

No luck.

netconsole works, but the if the network interface is left up (as is needed by
netconsole) the system freezes on the way into suspend with the following on the
screen:

[ 290.147733] Stopping tasks: ==========|
[ 290.151845] GTM info 78,78,258,258,12

<4>[ 295.204252] NMI Watchdog detected LOCKUP on CPU0

(the last 2 lines were not transmitted over the network)

If the interface is downed then I get no messages on the way down or up, of
course, and the crash occurs the same way as usual.

Any ideas?

Is there a way to put the console on a parallel port and connect the parallel
port to another computer? Is there a driver to send console messages over a
LapLink (null-printer) cable to another computer?

Sorry for all this mail.

Is there any motion on this problem? Is there anything I can do to help?

I know you are busy with other preperations for the release. Sorry to bother you.

Sorry, but (basically) we probably need to know what the kernel was doing (if
anything) when it wakes up. I appreciate that this is difficult to track down.
The one thing that's worth trying is to boot with the init=/bin/bash option on
the kernel command line, which will drop you to a shell. Suspend by doing

mount /proc
echo -n 3 >/proc/acpi/sleep

and see if it resumes without a flashing caps lock key. If so, that tells us
that the crash is probably triggered by one of the modules you normally have
loaded. Now you just need to figure out which one...

[Arthur Peters (amp)]

OK, I did want you said and it does the same thing: Disk light comes on, stays
that was for maybe 20sec then the capslock starts flashing.

I also tried booting with init=/bin/bash then unloading as many modules as I
could (all but the ide stuff and unix socket support). Sleep still gives the
same result.

Is there anything else to try? Is it actually possible to get oops via morse
code on the capslock light? I don't want to do that, but if that is the only
option I'll do it.

Could bypassing the initrd help?

I'm just trying yo think of things.

This bug is still present in Dapper Flight 2.

I will put in some more effort to try to get the oops out of the system somehow.

[Len Brown (len-brown)]

What is on the screen upon resume?
If you suspend in VGA mode do you see the oops?
If yes, can you take a photo of it?

[Arthur Peters (amp)]

The screen never shows anything and the backlight never comes on. I've looked closely to see if there is an image but no back light, but there is no image.

What do you mean by VGA mode? I've tried booting with init=/bin/bash on the kernel command line and then running "echo -n 3 > /proc/acpi/sleep" and I get the same crash.

Thanks.

Welcome to the most commonly reported
Linux suspend-to-ram bug on Earth --
no video video on resume from S3.

Note that laptops that support Linux are
required in the BIOS to restore video
on resume from S3. This of course, is
of small consolation, since almost zero
laptops _officially_ support Linux...

There are workarounds listed in the source tree
Documentation/power/video.txt that help
many systems.

http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;h=912bed87c758457b2f42b6decb1964326efce3de;hb=3ee68c4af3fd7228c1be63254b9f884614f9ebb2;f=Documentation/power/video.txt

Yes, VGA mode is what you were in when
you booted the shell -- no X is running.

I got access to a compaq presario R3000
and found the same failure as you.
Then I ran it in a docking station where i
had a serial console and that told me that
it took a machine-check-exception shortly
after resuming to the shell prompt.

There has been some changes on this problem. It can now sleep!!

Just click System -> Quit... -> Suspend on the live CD. However, this does not work in installed system. This seems to be caused by the fact that the "nvidia" kernel module is loaded in the installed version, but not in the live CD environment. Unloading it in single user or full X mode allowed suspend to work (just by clicking System -> Quit... -> Suspend).

Since by default the nvidia module is loaded but not used. I'm not sure where it is being loaded (I blacklisted it in /etc/modprobe.d/blacklist and it didn't prevent it from being loaded), but maybe it should not be loaded so as to allow suspend to work. nvidia-glx is not enabled be default anyway.

I tried to get the nvidia driver to sleep by using the NvAGP option, but it did not work.

This is fixed in Edgy RC. It suspends correctly out of the box.

Hi guys,

I'm not going to add anything fundamental to this topic, just something possibly usefull to other people dealing with suspend-to-ram problem: in its last post Arthur wrote

** This is fixed in Edgy RC. It suspends correctly out of the box. **

but this is just partially true. In my case I had to make some changes to /etc/modules and /etc/default/acpi-support to have my NVIDIA card correctly waken up after sesume. All those changes are perfectly documented at this link:

<a href="https://help.ubuntu.com/community/NvidiaLaptopBinaryDriverSuspend">NvidiaLaptopBinaryDriverSuspend
</a>

ATI card owners should take a look at this other link:

<a href="https://help.ubuntu.com/community/SuspendHowto">SuspendHowto</a>

I hope this will be usefull to some of you out there.
