Thinkpad T450s unable to resume after suspended for a long time

[Pinghao Qi]

My laptop shows a black screen when resumes from suspend. I'm unable to log in with ctrl-alt-f1 then ctrl-alt-f7. I'm able to control the keyboard backlight, the LED on the power button still looks like the way the laptop is in suspend. I'm only able to log in by pressing the power button and power off.

This issue only happens when I close the lid and leave the computer for a long time. If I close the lid and open it in around 1 minute, it resumes just fine. I have to press the suspend button in the drop down menu to suspend the laptop first, and then close the lid. In that case, the laptop resumes without error. I've set in the power settings to let the laptop do nothing when lid is closed, and that didn't change the problem.

I've tried using the newest i915 driver from o1.org and the same problem persists. This same problem is observed in clean installs of 14.04LTS, 14.10 and 15.04. I updated to 15.04 from 14.10 using the built-in updater.

WORKAROUND: In BIOS, disable Intel Rapid Start Technology.

pm-suspend.log shows this error line. Everything else is success.

Running hook /usr/lib/pm-utils/sleep.d/60_wpa_supplicant suspend suspend:
Failed to connect to non-global ctrl_ifname: (null) error: No such file or directory
/usr/lib/pm-utils/sleep.d/60_wpa_supplicant suspend suspend: success.

It seems this bug has been reported in many places since a long time ago.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

After some preliminary testing with kernel 4.0, it seems that the bug is fixed. I'll do more testing tomorrow. However, I've been getting the following error message at startup when using kernel 4.0.

Error parsing PCC subspaces from PCCT.
Starting version 219
thinkpad_acpi: unsupported brightness interfaces, please contact <email address hidden>

It doesn't affect anything of the system so far.

[Pinghao Qi (feifeiqph)]

After more testing, I left the laptop in suspend overnight with kernel 4.0, and it fails to resume in the morning. So the same bug still exists in kernel 4.0.

[Pinghao Qi (feifeiqph)]

After more researching and testing, I've determined that the bug is caused by the Intel Rapid Start technology in BIOS. It had a timer of 3 hours after laptop sleeps. I disabled that in BIOS and resume from suspend started working just fine. I don't know if this is a Ubuntu bug or a BIOS bug.

[penalvch (penalvch)]

Pinghao Qi, just to clarify, were you testing kernel 4.1-rc1 or 4.0.x?

[Pinghao Qi (feifeiqph)]

I was testing with the newest 4.0 stable kernel.

[penalvch (penalvch)]

Pinghao Qi, just to advise, 4.0 is not the latest mainline kernel. Hence, could you please advise to the results requested in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1449357/comments/4 ?

[Pinghao Qi (feifeiqph)]

So I tested with 4.1rc and it also doesn't work with intel rapid start. I set the rapid start timer to immediate in BIOS and as soon as I close the lid and open it back up, I was unable to resume to where I was.

[penalvch (penalvch)]

Pinghao Qi, could you please provide the missing information following https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[penalvch (penalvch)]

Pinghao Qi, the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list (platform-driver-x86 CC Matthew Garrett ) by following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel ?

Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked via http://vger.kernel.org/vger-lists.html . It can take a day for the new e-mail to show up in the respective archive.

Thank you for your understanding.
