[Acer Aspire 7250] Ubuntu Vivid Won't resume from suspend

[Kamakwazee]

My hardware: https://gist.github.com/anonymous/5a51cfb83206b4921024

I am using the most recent version of the development version of Ubuntu Vivid. I suspended my laptop, waited 10 seconds, and attempted to start back up, and all I received was a black screen.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 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.

Tabor Kvasnicka, did this problem not occur in a release prior to Vivid?

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

[Kamakwazee (kamakwazee)]

I'm not sure as I rarely ever used suspend. I used it solely for testing purposes. Further observation has made me see that it appears that rather than being unable to resume, it seems that it is unable to suspend. I have compiled some of the data that you have requested. In the mean time, I will run another test case to rule out the issue just being my lack of patience.

[penalvch (penalvch)]

Tabor Kvasnicka, for regression testing purposes, could you please test 12.04.0 (kernel 3.2.x) via http://old-releases.ubuntu.com/releases/12.04.0/ and advise to the results?

[Kamakwazee (kamakwazee)]

Absolutely. And I can confirm that the issue is not due to my lack of patience. It seems that it doesn't completely suspend as the power light doesn't turn off. I will download and test the iso.

[Kamakwazee (kamakwazee)]

It still did not work in 12.04; however, it did fully suspend; it just failed to start back up.

[penalvch (penalvch)]

Tabor Kvasnicka, the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list 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.

Thank you for your understanding.
