My T42 doesn't even go to sleep fully. The screen blanks, hard disk spins down, and the little moon LED lights up, but the fan never stops spinning, and I can press Caps Lock and see the LED light up. The moon LED remains lit up, and the screen remains blank, even if I try to wake it up by pressing Fn or opening the lid.
I can also reboot my laptop with Alt+SysRq+S, U, B while it is in this half-sleep state.

i have to agree with Marius here, i thought the laptop suspended fully in my original bug report but now i can see that it doesn't even do that as i can activate the thinklight and the fan keeps running on my T30.
so i guess as Marius said, its in a 1/2 suspended state.
I also dont have the libata module loaded on my system as the T30 doesnt have sata hardware..

Ditto on my t43. Probably not related to the libata patch, as that patch affects resuming from suspend, while this bug means the affected computers won't even suspend fully.

After numerous hours of reverting commits, building, compiling, installing, and attempting to suspend, I can rule out with certainty any libata, usb, and pci restoration changes as culprits.

Peter: Did ACPI suspend work for you before the -25 kernel update? If not, I'd say you have a seperate bug. Seeing that your A20 uses APM by default, ACPI is probably broken in general for your machine. If this is the case this bug should remain marked as fixed.
Peter Whittaker (pwwnow) wrote : | #36 |
I've always had mixed results with ACPI with Dapper - IIRC, ACPI worked better in Breezy. You are right, the Ubuntu default for this machine is APM (because of the age of the BIOS). However, under Windows, the A20m uses ACPI and it works like a charm.
So the A20m doesn't "use APM by default": during boot, HW detection simply indicates that this machine fails a cutoff - because of the age of the BIOS, Linux chooses APM. I've never been happy with that "logic".
If this is another bug, then, yes, let's revert status to fixed release. Is there a consensus on this?

Since I ran into this, I have done a complete fresh install of edgy. The problem disappeared with the fresh install. That leads me to believe that this is one of:
- Differences between the resulting images of upgrade and fresh install
- Problems introduced by one or more of the ACPI settings changes
- Incompatibilities caused by specific packages, such as that which would exist with mysql if the ACPI scripts weren't deliberately working around it.
For reference, I'm on a ThinkPad T42p, and the ec_intr=0 workaround had no effect.
TuxMe posted this workaround which I have not tried, but I don't see it listed here, so just in case it works for somebody... "[...] you might try appending the following parameters to your kernel entry in /etc/boot/menu.lst:

Wierd, I don't have 6.10 on my R60 but on my R51 6.10 works with the
adjustment that you're talking of. I first installed Kubuntu Edgy 6.10
beta, first it worked with the adjustment, then it stopped working after
some system upgrade, then again with a later upgrade it started working
again. (I always kept my added kernel parameter in the GRUB
configuration.) Sorry I didn't register any details about the different

Since this looks like an ACPI issue, I checked the ACPI website:
Their bug tracking system asks that you /not/ report bugs there that
aren't vanilla kernels. (I suspect the Ubuntu one isn't). However, they
do provide details about what debugging feedback they need to track down
issues:
* The output from dmesg -s40000 or the serial console log
* The output from dmidecode, available in /usr/sbin/ or at
savannah.nongnu.org or at kernel.org
* The output from acpidump, available in /usr/sbin/ or in the PM Tools
at kernel.org
* Please attach the output from lspci -vv and cat /proc/interrupts
( In the HTML version on the site, they provide links to get the
non-standard utilities they reference ).
So to the other bug reporters: It would be useful if you post requested
details about your systems.
With some of that gathered, perhaps we could point the ACPI developers
to this ticket and they would be willing to help. (Since I'm also
experiencing a similar regression on new Mandriva's I assume this is
actually an upstream issue and not a Ubuntu issue. )
Thanks!

Status update. I found some related info. and made some progress on fixing the Suspend feature on my laptop. My laptop has an ATI graphics card. When I was using Dapper, I had enabled hardware 3D acceleration by using the ATI proprietaty driver. When I upgraded to Edgy, I lost the 3D support because the configuration went back to using the open Ubuntu graphics driver. So I followed the steps under https:/

With the radeon dirver the system resums from Suspend but not the display. The screen is black and Strg+alt+del reboots the system.

ACPI Hibernate (or Suspend-2-Disk) doesn't work especially well on my Thinkpad T60p. It sometimes wakes up, but it takes really long, and I don't necessarily get all my drivers back (including wireless networking). However, sleep (to RAM) *does* work, including the Fn+F4 combination, and it automagically comes back after opening the lid just fine.

ThinkPad A20m running 2.6.17-10-33, all stock, no special patches or packages (FWIW, HWDB 2ad3fb6ba7d8b4d
At boot, all works well. S3 sleep (suspend-to-RAM) works well and reliably. S4 hibernate (suspend-to-disk) also appears to work well (I've only used it a few times, I tend to use S3 exclusively). I can S3-and-resume repeatedly, with consistent results, as described herein.
Upon resume, "almost all" things work well.
Three remaining problems are:
1) Network isn't visible right away: There is a lag (a few seconds at most) between the machine waking up and Ethernet (eth0 Ethernet) being available. By the time I unlock my screen, the network is available (and I unlock as quickly as I can).
(This appears as an immediate error in Evolution: It attempts to retrieve and cannot resolve mail server addresses. E.g., when I dismiss the Evolution error dialog and immediately send-receive, all is well.)
For me, this is a nuisance more than anything. For someone with an unattended machine waking at a set time, this could be a major stumbling block.
2) No sound. Comes back when I reboot. One exception, booting with noapic and pci=noacpi, see below.
3) Video playback is "blocky", that is, all videos play in extreme slow motion and playback is jumpy. It can take 5-10 seconds to play a single second of video.
Other points of interest:
I am booting with ACPI=force, since thinkwiki.org recommends ACPI on this machine and since the machine appears more responsive when running with ACPI rather than APM. However, all problems described above occur with both APM and ACPI, and all features appear to work equally well under both power management schemes (S3, S4, etc.).
To workaround the problems described above, I've tried booting with various combinations of
noapic, nolapic, and pci=noacpi
and various combinations of
ec_intr=0, lapic, and pci=routeirq
all with ACPI=force.
None of these combos make the slightest difference, behavior is as described in this report. (I haven't yet tried adding pci=noacpi to the second combo set, i.e., with ec_intr=0 and pci=routeirq, but at this point, after dozens of reboots and S3s and resumes, I don't know that I will. Any guidance as to which combo might be worthy of further testing would be much appreciated).
To make it clear, for each set of 3 options, I've booted with all 7 possibilities, and have not been able to detect any improvements. The one exception is that sound was OK upon resume when I booted with noapic and pci=noacpi; other problems remained as described in this report.
One combination made things worse: Booting with noapic nolapic pci=noacpi broke S3, I could not suspend at all. The machine tried, but came back immediately.
Finally, I should note that my /etc/default/

For reference, Mandriva solves sound-after-suspend with some shell
scripts that remove and reload some sound modules, as well as possibly
restarting some programs using the sound device. This has worked
reliably for me on a T20 with 2006. The scripts they use are GPL and
available here:

All video, or just DVDs? I noticed and documented that "DMA" doesn't
seem to come back after a suspend on the ThinkPad T20, which is the
cause of DVDs not playing well after suspend/resume.

Update: Booting with ACPI=force and ec_intr=0, I've now tested all
combinations of pci=noacpi, pci=noacpi, and noapic (that is, I use
ACPI=force and ec_intr=0 on all boots, and booted with the 7
combinations).
Result: Six out of the seven combinations work the same as described in
my 'Edgy on A20m "almost" works' report, above. That is, S3 and S4 work,
resume works, but upon resume, video playback is blocky and the network
wakes up "late".
One combination made things worse: When I boot with "acpi=force
ec_intr=0 pci=noacpi", the system become unresponsive upon resume from
S3 sleep. Load average spiked at 15, was never lower than 7, and typing
was painful. I had to BRS (big red switch). Good thing Evolution has a
recovery feature, otherwise I would have lost most of this report....
To summarize:
ThinkPad A20m "likes" 2.6.17-10-386 and "likes" ACPI:
"Almost everything" works, there are couple of things
that don't work after a resume, as described above,
and the system seems more responsive under ACPI than
under APM, at least until the first S3. Upon resume,
system responsiveness seems about the same with both
ACPI and APM.
One last misc note: On the A20m, booting with lapic disables APIC. The
BIOS disables lapic (hadn't realized this until yesterday), and when I
boot with lapic , there is a message in the kernel log that Linux was
unable to initialize APIC.

As for suspend to RAM on my Toshiba Portege M200 with Edgy: it will wake up
immediately after suspending (or more appropriately, I dont think it actually
suspends, as the suspend LED doesnt ever go on).
If I manually *unload* all usb modules except usbcore with modprobe before
suspending, suspend works just fine (like in Dapper, even faster possibly)!
But obviously after resuming I won't have USB mouse and keyboard anymore.
I'm looking into automating this process with powersaved.

Ok, on my laptop (Toshiba Portege M200) the following works:
Install powersaved if you don't have it already.
Edit /etc/powersave/
Change
UNLOAD_
(possibly it's commented out, if so, uncomment it or has some modules in there
already, if so, you might want to keep them)
to something along the lines of (you might need other modules depending on
your hardware configuration)
UNLOAD_
ohci_hcd uhci_hcd stir4200 ohci1394 ipw2200 rt2500 prism54 ath_pci r8169
lt_modem Intel536 Intel537 ndiswrapper"
needs all be on ONE LINE.
Then try running powersave --suspend-to-ram.
For me, that did the job.
If you're a KDE user, also get kpowersave, quit guidance-powersave and start
knetworkmanager instead. I don't use gnome so I can't tell what
infrastructure you need.
If you run into issues with your display, you might want to install suspend
(especially the s2ram app) from suspend.sf.net. Just shout if you need help
with that.

This is not necessarily true. Lately I don't think I've had to re-add the boot parameter upon upgrading the kernel. Let's say, if you experience problems after upgrading the kernel then check that you've still got your ec_intr=0 boot parameter in place. :-)

Hi, as workaround, did you try switching to a text console (ctrl-alt-F1)
and back?

It seems to me that at least with my ThinkPad R60 and the newest Ubuntu Edgy kernel (2.6.17-11) I'm better off not using the ec_intr=0 parameter at all. Cause suspend to RAM seems to work with the default kernel parameters, but stops working with ec_intr=0. (I just figured this out, so I'll let you know if suspend to RAM starts turning evil on me again. But for now it seems to work repeatedly...)

I did try that after you suggested it, it didn't help any. The screen still
just stays black with the cursor able to move but nothing else happening and
GNOME not coming back. If it helps you any, I am using the nVidia restricted
drivers with Beryl and Emerald.

Suspend-to-RAM successfully suspends the computer, but it fails to resume. I am left with a blank screen (no hard drive activity) and no backlight.
Suspend-to-disk fails more than it succeeds. Though, I've had luck with it on occasion.

For new people posting to this bug can you please make sure that you can reproduce the problem:
o When beryl/compiz/
o Without _any_ binary drivers running.
Unless you are using the same (or extremely similar) hardware and BIOSes as the people originally reporting this bug your suspend issue is almost certainly different and you are probably better off looking for a bug that better matches your system or filing a new bug and carefully detailing your system.

My suspend worked in 7.04 when in metacity, however right after the upgrade to 7.10 my suspend will not function even while in metacity. I am running a Dell XPS M1210.

Just wanted to report that with Kubuntu 7.10 my Thinkpad X41 still does not suspend to disk.

This bug has been "In progress" forever. Is it really in progress?
The latest kernel sometimes kills the network connectivity after hibernating or sleeping on a TP X41 and a TP T41. ifconfig does not show any network interfaces apart from loop. A reboot fixes it. I don't like it. :)

Bug 92461 may be a duplicate of this bug, or at least related to this bug. Can anyone confirm? Thanks.

Hi All,
I'm afraind that this report may have gotten a bit off track and therefore difficult for the development teams to debug. The symptom of this particular bug, failure to Suspend, is specific to the hardware used. So while many of you may have the same symptom they really should be different bugs. Also, the original bug reporter has commented that issue was resolved for them (https:/
If you are still experiencing issues, it would be helpful if you could test with a Hardy Alpha build, http://
