It certainly looks like a kernel regression, but it's difficult to say what's wrong without narrowing it down. Would you be able to build a kernel from kernel.org? I will try. Thanks. Sorry, I can build Linux kernel (2.6.31.6) on my notebook, too much disk space required (about 4G free space left) to build the kernel. It's not easy for an old notebook to build a Linux system. It's an 5 years old IBM ThinkPad R51 with 30G hard disk, installed Windows XP and Ubuntu. Ubuntu is on a 10G partition. Is there some parameters can be configed that let the build process to use fewer disk spaces? Thanks. More details in this Ubuntu bug comments: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/485108 I just got an IBM ThinkPad T42 (40G disk, it's almost full now), and will get a T43p in next week hopefully. The T43p has a 60G disk and I will try to build the 2.6.31 kernel on that machine. any update? On Launchpad.net I was encouraged to browse the bugzilla.kernel.org database to file a new bug and link it to the bug I reported back in November, 2009. However, I fond this one matching my and many other users' issues detailed at this address: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/485108, as already reported by Wayne. This issue affects several systems besides Thinkpads, and is not isolated or hardware-specific. I've already submitted some data to the developers as part of the routine bug report procedure, but would be happy to help should you need more specific data. Also, many more users experiencing this issue on different systems subscribed to the bug report and are likely to provide more data, if asked to. suspend/resume bugs are mostly platform specific. My question is: are you sure you have the same problem as this one? (In reply to comment #0) > I have tested with kernel 2.6.30, 2.6.31.6, 2.6.32.rc6/rc7 and found that it > works on release 2.6.30, but failed on all other version greater than 2.6.30. > (I used binary kernels download from Ubuntu kernel site: > http://kernel.ubuntu.com/~kernel-ppa/mainline/). does your laptop also work in 2.6.30 and fail in other kernel releases? If yes, it would be great if you can use git bisect to help us narrow down the problem. If not, I suggest you to file another bug report and give a detailed description on the problem you encountered. please attach the dmesg output and acpidump output of your laptop in the new bug reports as well. Yes, it works on 2.6.30 and failed on any release > 2.6.30. I kept trying any new updates of release of 2.6.31, 2.6.32 and 2.6.33 but neither of them work. I have got 2 ThinkPads with larger hard disks now, would you please give me some suggestions on what should be configured to the build, for example: Which version should I use? What build configuration parameters should be set before build? I am not very familiar with Linux kernel build process, even though I have developed C++ application on Unix in 90s. I am using Java now, which the is much simpler. Thanks, Wayne The problem happened when I upgrade my laptop from Ubuntu 9.04 (kernel 2.6.28) to Ubuntu 9.10 (kernel 2.6.31). When I use kernel 2.6.30 with Ubuntu 9.10, suspend/resume without any issue, but applications with video playback, for example Flash playback in Firefox, any movie player (VLC, MPlayer) will crash, and there is no audio. May be audio and video (X server and drivers?) using some feather of kernel 2.6.31. So using kernel 2.6.30 is not a workaround. This is really an annoying bug introduced in release 2.6.31, it makes the system almost isn't usable because you have to power off the system when suspend hangs, and suspend is quite frequently for a laptop system. It's definitely a kernel bug (regression) because I have found there are other reports of this issue on other Linux distributions with kernel 2.6.31, such as Fedora 12 and OpenSuse. Even though there are other brands encountered these issue, but ThinkPad is brand that failed most frequently. Almost any series (R50,51,52, T40,41,42,43, X..) for both old and new, the IBM's and Lenovo's. Is there any special component that ThinkPad have and other brand don't have usually? I found that ThinkPad ACPI system is special (http://ibm-acpi.sourceforge.net/), is there any significant change on this driver or other module that ACPI depend on in Linux kernel 2.6.31? That may be a hint. (In reply to comment #8) > suspend/resume bugs are mostly platform specific. I believe you. However, most comments here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/485108 seem to disagree. > My question is: are you sure you have the same problem as this one? > > (In reply to comment #0) > > I have tested with kernel 2.6.30, 2.6.31.6, 2.6.32.rc6/rc7 and found that > it > > works on release 2.6.30, but failed on all other version greater than > 2.6.30. > > (I used binary kernels download from Ubuntu kernel site: > > http://kernel.ubuntu.com/~kernel-ppa/mainline/). > > does your laptop also work in 2.6.30 and fail in other kernel releases? Yes, I am sure. As I already wrote, my Thinkpad R50e resumed from Suspend mode flawlessly under Intrepid and Jaunty, whereas under Karmic my laptop never actually suspends anymore, nor hibernate, for that matter. Indeed, in case it helps, if you actually click on the above address and follow the links related to serious kernel problems, you might get a wider picture of the connection between the serious kernel problems and the "suspend/resume failure" (Bug #488673), or "hibernate/resume failure" (Bug #493505). I'm not sure they're all related, but never had any of those before Karmic. > If yes, it would be great if you can use git bisect to help us narrow down > the > problem. I have tried to solve the issue, but when I saw no solution I started using my desktop computer, for I frequently need those features for work. If needed, I will use it again to help you narrow down the problem, but will need guidance, for I don't know what "git bisect" is, and my technical knowledge of ubuntu and its inner workings is very limited. > If not, I suggest you to file another bug report and give a detailed > description on the problem you encountered. > please attach the dmesg output and acpidump output of your laptop in the new > bug reports as well. I believe it is indeed the same bug, which Apport indicates as a serious kernel problem. If from the description and the comments on Launchpad you believe otherwise, please let me know, I will be happy to follow your suggestion. Please provide some more detailed hardware information. What chipset is that, what CPU, what graphics etc. (In reply to comment #13) > Please provide some more detailed hardware information.

some more detailed hardware information. What chipset is > that, > what CPU, what graphics etc. Hi Rafael J. Wysock, I think if this bug is caused by hardware, it's not "normal" hardware such as CPU, graphics card etc, if should related to SPECIFIC hardware that only ThinkPad has, for example bios (IBM has specific ACPI characters, isn't it?), security chip etc. Because almost all series of ThinkPad fails (R, T, and X series as I know), and they uses wild range of CPU and graphics (R51 use embedded Intel graphics, T42, T43 use ATI FireGL grachics). I suspect some ThinkPad-ACPI changes cause this issue. There is a ACPI change in release 2.6.31 for LED status: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f21179a47ff8d1046a61c1cf5920244997a4a7bb and when resume fails, the SEMI MOON LED flashes in an extremely high frequency and the system die. Cheers, Wayne then does the problem still exist if you blacklist the thinkpad-acpi driver? I assume the S3 on your laptops used to work w/o this driver. The following is the models of ThinkPad that failed from Ubuntu bug database (not completed): https://bugs.launchpad.net/ubuntu/+source/linux/+bugs?field.searchtext=thinkpad+suspend%2Fresume+failure&orderby=-importance&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHOUT_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package= IBM Thinkpad T41p IBM ThinkPad T42p IBM ThinkPad T43 IBM ThinkPad R50e IBM ThinkPad R51 IBM Thinkpad G40 IBM ThinkPad X31 IBM ThinkPad X40 IBM ThinkPad Z60m LENOVO ThinkPad T60p LENOVO ThinkPad T61 LENOVO ThinkPad T61p LENOVO ThinkPad T400 LENOVO ThinkPad T400s LENOVO ThinkPad T500 LENOVO ThinkPad R61 LENOVO ThinkPad X61s LENOVO ThinkPad X200 LENOVO ThinkPad X200s LENOVO ThinkPad X200 Tablet LENOVO ThinkPad X300 LENOVO ThinkPad SL LENOVO ThinkPad Z61p LENOVO ThinkPad W500 Almost all models of ThinkPad both IBM and Lenovo fails. There are lots of system log in these reported bugs (generated by Linux), but it seems there is no useful information about the suspend process. Is it possible that some kernel expert analysis these logs? Cheers, Wayne (In reply to comment #16) > then does the problem still exist if you blacklist the thinkpad-acpi driver? > I assume the S3 on your laptops used to work w/o this driver. Hi Zhang Rui, Would you please tell me how to disable this driver? Thanks, Wayne If it's loaded as a module, please add "black thinkpad_acpi" in /etc/modprobe.d/blacklist.conf and then reboot. If it's built it, please reboot with this boot option, thankpad_acpi.hotkey_report_mode=3. (In reply to comment #19) > If it's loaded as a module, > please add "black thinkpad_acpi" in /etc/modprobe.d/blacklist.conf and then > reboot. > If it's built it, > please reboot with this boot option, thankpad_acpi.hotkey_report_mode=3. Thanks for you advice. It still failed even disabled thinkpad_acpi. It's seems not the issue of ThinkPad acpi driver. (I tested by rmmod thinkpad_acpi and with kernel option you told me. It's build in) I also tested suspend with PM_TRACE enabled (sync;echo 1>/sys/power/pm_trace;pm-suspend), and attached the dmesg when system die and rebooted. Would you please check if there is any useful information? There is no suspected driver reported (as 'hash matches' described in the document). Thanks, Wayne Created attachment 25222 [details]

FYI Hibernate works fine even though suspend failed on my ThinkPad R51 with Ubuntu 9.10. Also joined this site here because of having the same problems as Wayne. A little bit funny, just noticed that hibernation works after I read Wayne's comment. Well, just wanted to let you know that indeed hibernation works on R51 (mine is a R51-2888). And the method described on the Ubuntu-homepage for getting a demsg works, but delivers no information like a 'hash-match' for me, too, like Wayne said before. Hey, found here something really interesting: After I read this here, https://bugzilla.redhat.com/show_bug.cgi?id=539367, I also tried to set 'nomodeset' in Grub, and supending worked suddendly! I don't know what happens when setting 'nomodeset' in Grub, but WLAN and other things continue working so...I think that's a good workaround :) 'kay, just noticed that it disables video-playback because of disabling KMS, so...what now? =/ Reassign to the Intel graphics people, I guess. It's NOT Intel graphics specific bug I guess. ThinkPad R51 uses Intel graphic card, but ThinkPad T42(p) and T43(p) use ATI graphic card, and they are fail either. Some Lenovo ThinkPads (T61) that failed may use nVDIA card. If it's a KMS bug, then it may be in the shared code and not in Intel card specific code I think. So, now it would be good to know if setting 'nomodeset' in Grub at Thinkpads with ATI or nVdia graphics-chips helps there, too, wouldn't it? Well, yes. In the meantime, please check if commenting out the line .resume = acpi_video_resume, in drivers/acpi/video.c (line 89 in the current mainline) helps.

Video playback no problem, suspend works. I will upgrade my T43p from Ubuntu 9.04 to 9.10 and give a try. Cheers, Wayne I can't find the file. Please, write the entire location. (In reply to comment #29) > Well, yes. > > In the meantime, please check if commenting out the line > > .resume = acpi_video_resume, > > in drivers/acpi/video.c (line 89 in the current mainline) helps. Hi Leonardo, I have upgrade my ThinkPad T43p laptop from Ubuntu 9.04 to 9.10 and suspend works flawlessly. It seems that it is a Intel video card issue. Because there are some ThinkPad T42/T43 Ubuntu 9.10 suspend failure report on Ubuntu site, I installed Ubuntu 9.04 on my T43p directly and didn't install 9.10. Until I found NOMODESET workaround, I upgrade it to 9.10 and found it there is no suspend issue. My R51 don't have enough disk space to build the kernel, and I don't know if it possible to build it on my T43p and then install it on the R51 to test it? Or if somebody else to test if this change works? Thanks, Wayne I am currently about compiling my own kernel with the change mentioned by Wysocki 4 posts earlier and let you know if it helps. And for the video playback I am currently using xine-based apps like Kafeeine, they work flawlessly, but other apps, like totem, stop working when setting 'nomodeset' and disabling KMS with that =/ (In reply to comment #32) > Hi Leonardo, > I have upgrade my ThinkPad T43p laptop from Ubuntu 9.04 to 9.10 and suspend > works flawlessly.

Hibernation, however, is still malfunctioning, and often waking up results in a kernel panic (freeze + caps lock flashing). Also, the new nomodeset option seems to affect videos being played especially in Totem. When I play a movie and try to move the window, the video disappears behind a black square, and nothing much changes if I maximise it (sometimes some leftovers from other windows remain over it, as if it doesn't redraw correctly). While moving the window, video seems to reappear, but when I stop it's gone again, and only audio works. This is exactly the same as it was under Jaunty, which would be a regression in my view. If those videos are played in VLC the situation improves, but is still funny (if another window moves over it, the black screen reappears until VLC is moved again, or blue lines surround the window moving on top, etc.). So it seems this workaround would solve one issue, but would cause a new one. Well, if I didn't do any mistakes while the compiling-procedure, commenting-out the line resume = acpi_video_resume in drivers/acpi/video.c didn't do anything, as soon as I disable nomodeset in Grub (in my test-kernel with the out-commented line above and the standard-karmic-kernel 2.6.31-19-generic) the old standy-freeze comes up again. I wasn't quite sure how to comment out code in C/C++, I made it like in the other examples in the file, so it looks like this: [...] /* * Commenting out for testing on 03-March-2010 * .resume = acpi_video_resume, */ .notify = acpi_video_bus_notify, }, }; [...] I'm quite sure that is correct, so, commenting-out the line mentioned from R. Wysocki doesn't change anything I'd say.

Hi M. Burger, You comment out is correct. It seems a Intel video driver issue because I can reproduce it on my Thinkpad T43p (with a ATI FireGL video card) with Ubuntu 9.10, even thought there some suspend fail reports for T42p, T43 on Ubuntu web site. May it's other suspend issue that has been fixed on recent 2.6.31 kernel? I have noticed there are some suspend bugs been fixed such as close lid of notebook suspend failure. Cheers, Wayne > Hi M.

Ehm, have you done a mistake when writing your last message Wayne? Because you wrote it's an Intel video driver issue but in the same sentence you wrote you can reproduce this bug with a Thinkpad using an ATI FireGL card?
And I'm quite sure this bug hasn't been fixed yet because I also tried newer kernels (2.6.32 + *.33) and the problem still exists with them.

Sorry M. Burger, my mistake. It should be I CAN'T reproduce this issue on ThinkPad T43 (with ATI card). Suspend works flawlessly on T43. Cheers, Wayne ...Like I thought :) So, what now? With Ubuntu 10 KMS will be essential needed (I read in the net sth. about the X-Server and the Intel-driver will require it and can't work without it) so I think this bug's solution is high-needed. If you need more information for fixing this issue just let me now... Facing Ubuntu 10, I'm hoping this gets fixed in the next time =/ But at this time, thanks for any work you've already done, I use Linux for about 3 years and still loving it :) Any news, or is this issue "fixed" by removing support for the i855-graphics-chips? =/ No, not removed. Abused maybe, but not killed outright. Maybe Yakui has an idea. I have same issue with a Thinkpad X41 after upgrading. Can we get some indication of any progress on this bug? Please? Its holding me back from upgrading my main Hardy system. If it broke after an upgrade you should be able to bisect the offending commit. Could be a dupe of: https://bugs.freedesktop.org/show_bug.cgi?id=22126 please check the patch in that bug. |
