suspend/resume fails on second attempt in LNXVIDEO:00
I'm trying to debug a resume problem on a compaq presario C700 laptop on the Ubuntu 2.6.24-22-generic kernel.
I've used the /sys/power/pm_trace facility to debug the problem to the following:
[ 31.212062] Magic number: 0:716:374 [ 31.212115] hash matches /build/buildd/linux-2.6.24/drivers/base/power/main.c:97 [ 31.212255] hash matches device LNXVIDEO:00
Not sure where to go from here though. Devices in this machine are:
00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev f3)

These symptoms mirror a lot of other reports with this machine in that the first suspend/resume cycle works but a second attempts (apparently) suspends fine but fails on resume. The backlight on the video does not come back and neither does the wireless connection, so I'm not positive the problems are purely video related.
How can I proceed from here to further debug what kind of workarounds or solutions I might be able to use to get reliable suspend/resume functionality?
Thanx,

not too sure what the situation is for you, but
if you're deciding to stay with 2.6.24.* then
look through the commits to see if this has been resolved. if not then load the latest git to see if this has been committed for the fix. if it's just debugging then hmm.. maybe ssh (but you don't have intranet upon wakeup); maybe usb
or some other hard wired mechanism?

Well, I've just built and installed 2.6.28-rc8 and the problem persists.

Right. It's for all intents and purposes "dead" on resume. Even CAPSLOCK on the console does not active the LED.

I'd hoped to do serial console, but sadly, this laptop, like many today doesn't have even a single serial port. I had considered a USB serial and making it console (if even possible) but now I am just spending more money trying to get this stupid laptop working. ~sigh~

From over here with a macbook(no serial port as well) making debugging intricate to the extent.
With running radeon it's weired,
if I do an echo mem > /sys/power/state
upon wakeup I'll have a black screen,(intranet works) but if I do a s2ram "poof" like magic it works.
if using (sorry for the word) fglrx, echo mem
works. haven't tried s2ram with that though.
Aside note glad to see you're running the latest kernel. for the past week or so there was posts about suspend but haven't kept up(was busy looking at SELinux refpolicy UBAC) maybe there was some talks or even some patches submitted for what you're dealing with?

Unfortunately that was of no help. Still only a single suspend/resume cycle worked. I removed it before the first cycle, (and made sure it was not loaded before the second) for the record.

Does it also happen in the minimal configuration (ie. with init=/bin/bash)?

Now, that's an interesting result. Using the above, pm-suspend does suspend fine and hitting the flashing power button will resume fine with the exception of the screen is still black. That is backlight problems isn't it? I can see by disk light activity though that it's actually still alive though.

No, most probably your graphics adapter is not handled correctly in this case, because it needs some special user space quirks, which are done by hald that is not running.
You can try to use the s2ram binary (http://en.opensuse.org/s2ram) to work around this issue.
Anyway, if you suspend for the second time from this state, does it resume?

That sounds like I am setting for something less than optimal. Is that the case? Why would I want to use what I've been trying to get working rather than s2ram? Maybe put another way, why isn't everyone using s2ram?
Ultimately I'm going to want to be able to suspend as well as hibernate, for whatever that's worth.

Because the hal-driven whitelist allows us to match systems in a more detailed way. If your system is in the s2ram whitelist already and works with it, there shouldn't be any difference.
Still, I was only considering that as a debugging aid in your case, because s2ram works in the minimal configuration, while hald doesn't.

Unfortunately, Ubuntu in their "wisdom" removed s2ram and claim "s2both" supersedes it in that it does both suspend to disk and suspend to ram and then suspends, but if your battery dies while suspended you can still resume from the suspend to disk.

Right. I will give s2both a try and see what happens... no joy. It fails to even run without the swap device mounted, and my swap device is not big enough to hibernate to anyway. Damn you Ubuntu.

Hm, this really isn't reasonable. s2both saves the image, which takes quite a lot of time, while s2ram doesn't. Also, s2both is not really ACPI-compliant.

You can compile s2ram from sources, it's not too difficult.

Hm. Is that all loaded when you boot with init=/bin/bash (by which I mean the minimal config)?

Hm, this really isn't reasonable.
Many people agree with you. :-) There is a long bug open with ubuntu to restore this s2ram. They seem to be ignoring it though.

s2both saves the image, which takes
quite a lot of time, while s2ram doesn't.
Indeed.

You can compile s2ram from sources, it's not too difficult.
Yeah. I will probably just grab the debian package and dpkg-buildpackage it on my Ubuntu system.

It sure is. Most assuredly by the initrd. Debian/Ubuntu systems seem to put everything but the kitchen sink into their initrds. Which on the one hand makes them pretty portable and resilient, but on the other, yes, bloated.

Well, please remove as many modules as you can (using rmmod) and see if your second resume still fails.
Thanks,

Because the hal-driven whitelist allows us to match systems in a more detailed way. If your system is in the s2ram whitelist already and works with it, there shouldn't be any difference.
Unfortunately, Ubuntu in their "wisdom" removed s2ram and claim "s2both" supersedes it in that it does both suspend to disk and suspend to ram and then suspends, but if your battery dies while suspended you can still resume from the suspend to disk.
I seem to be missing the original message, but: no, s2ram doesn't exist in Ubuntu because pm-utils handles that role.

Well, that's *their* argument but lots of people think otherwise. There appears to be no shortage of people for whom pm-utils does NOT work yet s2ram does. https://bugs.launchpad.net/ubuntu/+source/uswsusp/+bug/134238
There is also indication earlier in this thread that it may work for me where pm-utils is not working.

The right answer to "This piece of software contains bugs" is not "Provide two pieces of software with the same features but different bugs". The only real functional difference between the two is that s2ram has its own internal whitelist rather than just using the hal entries. Suse have normally been good at making sure that they're synced across, but if that's not happening you probably want to poke them.

OK. I got the list of modules down to:
Module Size Used by ipv6 254836 14 ext3 130568 1 jbd 53908 1 ext3 mbcache 16004 1 ext3 loop 22540 2 sd_mod 41240 2 crc_t10dif 10112 1 sd_mod ahci 37260 1 libata 176160 1 ahci scsi_mod 156948 2 sd_mod,libata processor 49708 2 fuse 58780 3
and that still failed the second resume. Just to remind you, the first suspend/resume (echo mem >/sys/power/state) works, but the screen is black on returning from the resume. I can then (blindly typing) do a second suspend but resume still hangs the machine.

You can try to use the s2ram binary (http://en.opensuse.org/s2ram) to work around this issue.
OK. I've done my s2ram experiments and go no better than with pm-utils/ kernel mode suspend (where first suspend/resume works, second suspend works, but second resume hangs the machine). Here's the full array of suggestions on http://en.opensuse.org/S2ram and their results:
s2ram -f -a 3
- hung on first resume
s2ram -f -a 2
- restored first resume but no backlight
s2ram -f -a 1
- hung on first resume
s2ram -f -p -m
- resumed first time but console font changed
- hung on second resume
s2ram -f -p -s
- resumed first time but console font changed
- hung on second resume
s2ram -f -m
- restored first resume but no backlight
s2ram -f -s
- resumed first time but console font changed
- message "Function not supported?\nSwitching back to vt1"
- hung on second resume
s2ram -f -p
- resumed first time but console font changed
- hung on second resume
s2ram -f -a 2 -m
- restored first resume but no backlight
s2ram -f -a 2 -s
- resumed first time but console font changed
- message "Function not supported?\nSwitching back to vt1"
These were always booting with init=/bin/bash and removing all removable (i.e. unreferenced) modules.
Where I mention "console font changed" that means it reverted back to the font that it was in when it was booting the kernel. You see, Ubuntu, at some point through boot actually change the font to be a "leaner" (i.e. not so "fat") font. This is not to say that I am running on the console in a framebuffer (to the best of my knowledge). I believe this font setting is being done with a "/usr/bin/consolechars" tool.
Anyway, thanx much for continuing to look into this.
Cheers,

Yes, and that's why pm-utils should die: they have design problems (depend on hal, can't be pagelocked, unusable for suspend debugging).

When using ubuntu intrepid, s2ram did work, but instead of grabbing the package from ubuntu, I used Debian SID instead. (I have a tendency of mixing packages);

Just wondering if any of this experimentation is likely to help me or is this just a loser of a laptop that will be more trouble that it's worth trying to get to suspend? I can take it back to the store still. Maybe I should and try a different one?
Or does it seem like there still might be a relatively easy fix for this problem, which would be nice given that it was a pretty good deal (or was it?). :-)

You're not the only person having a problem like this and unfortunately it's not easy to debug. I don't know of any fixes available.

So I should probably stop holding my breath on this laptop and just go get a different one I guess. :-( Too bad. This is definitely a better laptop than I can buy otherwise for that money.
Maybe my wife will be happy to give up suspending for the better machine. Suspend is very nice to have though.
If there is anything at all I can do to help progress this along, I'd be more than happy. I've already built a kernel from source with the power management verbose debugging. I can apply patches and test easily enough if that helps in any way.
I certainly appreciate the effort you and everyone has already put into this and if goes no further than this, I certainly cannot complain that nobody tried to help.
Thanx!

Well , I am thinking if you have a intel-video , and yes ! , I am getting in a same kind of trouble, I bet that is a problem with i915 drm , mesa 7.2 and xorg-x11-drv-intel (or i810) .
Maybe you can try resume/suspend using vesa video drive, or without X.org running.

Not likely. I unload all of that before I do my tests. My tests are nothing more running that a shell (literally, that's the only process) and I have my module stack down to about half a dozen modules.
