This change was made by a bot.

I'm afraid that this is not reproducible on demand (it was reported automatically). I will have to observe it before I can do any sensible testing.

[Daniel Christian Henter (mr-ghettoblaster)]

I'm also affected but in my case it's reproducable every time I suspend

[Bryan Quigley (bryanquigley)]

@mr-ghettoblaster
In that case, please do try with a mainline kernel and see if it's still the case (see Christopher's instructions).

Just seen this again with Vivid.

[Michael Thayer (michael-thayer)]

For information, I am the original reporter. I set this to "confirmed" because I am still seeing the problem (not reproducible on demand, in fact only extremely sporadic) and one other person (mr-ghettoblaster) confirmed it. Is a new bug report still useful? If so, for my help in filing it, what advantages does it bring?

[penalvch (penalvch)]

Michael Thayer, it's a little confusing as you are logging into a different account then the one that originally reported the issue:
Original Reporter account -> https://launchpad.net/~michaeljt
Your second account -> https://launchpad.net/~michael-thayer

[Michael Thayer (michael-thayer)]

Sorry about that. This was one of about twenty automatic reports by Apport when I upgraded to Vivid.

[penalvch (penalvch)]

Michael Thayer, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.
