Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 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.

[emk2203 (emk2203)]

bug exists in kernels up to 3.16.0-11. 3.17.0rc2 fixed the issue.

[emk2203 (emk2203)]

My report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358647/comments/4 was premature. The bug is not appearing if I pm-suspend the machine, but entering sleep mode by itself caused the crash again.

[penalvch (penalvch)]

emk2203, let the scope of this report only focus on "entering sleep mode by itself", with the pm-suspend being a WORKAROUND to this.

Hence, was this reproducible in a release prior to Utopic?

[emk2203 (emk2203)]

Not sure, because the laptop never slept by itself, just monitor in energy save. Sleep is only forced by lid down or pm-suspend.

tl;dr: unsure

[penalvch (penalvch)]

emk2203, the laptop was released fairly recently (mid-2013), so let us put that aside for now. Lastly, could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc3-utopic/ and advise to the results?

[emk2203 (emk2203)]

Due to a hardware failure, Ubuntu was restored on the SSD of the machine instead of a native install on USB media. Suspend/resume now work properly.

[penalvch (penalvch)]
