Failure to suspend on Lenovo X230

[Joel Stanley]

My system tries to enter suspend, but bails back out with the following:

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 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.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1284372

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Attached is the dmesg output for 3.13.0-12 and mainline 3.14-rc4.

In both cases the system suspends the first time after boot, but subsequent suspends fail.

The mainline kernel doesn't contain the i915 backtrace, so perhaps this is unrelated?

[Joel Stanley (shenki)]

Taking a closer look:

[ 274.333064] pci_pm_suspend(): e1000_suspend+0x0/0x20 [e1000e] returns -2
[ 274.333067] dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -2
[ 274.333069] PM: Device 0000:00:19.0 failed to suspend async: error -2

If I rmmod e1000e before suspend the issue goes away. Interestingly, if I then re-insert e1000e suspend works.

This looks familiar:

Perhaps this is a dupe of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1250476?

[penalvch (penalvch)]

Joel Stanley, please execute the following at a terminal while booted into a Ubuntu repository kernel (not a mainline one):
apport-collect 1284372

[Joel Stanley (shenki)]

Hello Christopher,

As you can see in comment #6, the kenrel log for the Ubuntu kernel is attached.

What extra information do you require?

[penalvch (penalvch)]

Joel Stanley, please do not remove the tags I apply to this report. Please perform the requested actions as noted in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1284372/comments/9 .
