thinkpad w510 fails to suspend

[Jerome Lacoste]

I have a new thinkpad w510 and it doesn't suspend at all on ubuntu 10.10 (based off kernel 2.6.35).

When suspending I get to a state where the console is cleared, a cursor blinks on the top left, no more disk activity, wifi light is still on and keyboard is unresponsive.

I am running with nvidia drivers, but even with non proprietary module (nouveau?), I have the same behavior.
I tried suspending from the command line (https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume#Suspending from text mode): same behavior and nothing gets printed on the screen. I removed quiet and slash boot options to see if the pm-suspend in from CLI would display more. Nothing.
I tried without X running, pm-suspend with power-trace to 1, same thing. If I hard reboot and store the dmesg contents I see this:

[ 1.327028] PM: Resume from disk failed.
[ 1.327043] registered taskstats version 1
[ 1.327566] Magic number: 0:990:668
[ 1.327568] hash matches /build/buildd/linux-2.6.35/drivers/base/power/main.c:544
[ 1.327678] rtc_cmos 00:08: setting system clock to 1976-02-18 05:39:35 UTC (193469975)

I also sometimes get
dmesg3.txt:[ 1.321892] Magic number: 0:990:107

Not sure what to do with that.

I tried removing many kernel modules before using pm-suspend, same thing.

I tried acpi_sleep=sci_force_enable, because of: https://bugs.launchpad.net/ubuntu/lucid/+source/linux/+bug/532374/comments/125. No help.

I am going to try the stock kernel now.

More notes:

* thinkwiki page is from 2007 and nothing on w510 or T510
http://www.thinkwiki.org/wiki/How_to_make_use_of_Power_Management_features

* I am aware of: https://bugzilla.kernel.org/show_bug.cgi?id=15407 but this seems different

* I have bios 1.31 (almost latest, latest has according to README only support for newer CPUs).
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-74858#version

* I haven't found any quirks to play with in hal (such as in https://bugzilla.redhat.com/show_bug.cgi?id=230675 )

I've had the same Problem with my Lenovo W510 on Ubuntu 10.10. I think this Bug is not only a duplication of https://bugs.launchpad.net/bugs/522998 . Here are two reasons for my opinion (by the way, I've found a workaround):

1. The USB3.0 module "xhci" mentioned in the bug #522998 was not loaded on my W510 with Ubuntu 10.10 but the module "xhci_hcd" was and has to be unloaded.
2. Unloading "xhci_hcd" was needed, but could not solve the problem at all. Additionaly the module "iwlagn" has to been unloaded. So both modules prevent correct suspending.

The workaround I mentioned above was adding the line 'SUSPEND_MODULES="xhci_hcd iwlagn"' to '/etc/pm/config.d/unload_module'. After this suspending to ram and suspending to disk works fine for me.
Please contact me, if there is a need for additional information about my system and/or configuration.

With kind regards,
Michael Vetter

The fix that Michael Vetter described works for me, namely SUSPEND_MODULES="xhci_hcd iwlagn".

[Jerome Lacoste (jerome-lacoste)]

Michael, Edwin:
1. the module has been renamed. So it's normal that the command wasn't sufficient. Check the maverick release notes.
2. my personnal bug report has nothing to do with iwlagn, so it's clearly a duplication of #522998. So please open a particular issue (or find the proper duplicate?) regarding your issue with iwlagn. Maybe here ? https://bugs.launchpad.net/ubuntu/+source/linux?field.searchtext=iwlagn+suspend&orderby=-importance&search=Search&field.status:list=NEW&field.status:list=INCOMPLETE_WITH_RESPONSE&field.status:list=INCOMPLETE_WITHOUT_RESPONSE&field.status:list=CONFIRMED&field.status:list=TRIAGED&field.status:list=INPROGRESS&field.status:list=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=

The SUSPEND_MODULES="xhci_hcd iwlagn" workaround works for me on my 10.10 + W510.

Thanks!

[Jessie Morris (jessieamorris)]

By the way, in Natty (11.04), I had to remove the iwlagn part on the SUSPEND_MODULES while running the newest kernel. If I didn't, Network Manager would sit there saying, "Authorizing" forever.
