Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 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.

> Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

It is difficult to say because I have seen only one instance of this problem.

The same machine is running since a week with kernel 3.19 and the problem did not show up again.

[czigor (czigor)]

Having the same issue. It is accompanied by the screen going black for 1 or 2 seconds.

Linux 3.16.0-34-generic #47~14.04.1-Ubuntu SMP Fri Apr 10 17:49:16 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

[czigor (czigor)]

It occurs in approx every 2 minutes when the laptop is operating on battery. When plugged in, it happens much less frequently (3 times so far in an hour).

[Laurent Bonnaud (laurent-bonnaud)]

I am closing this bug because I never saw it again and kernel 3.16 is very old by now.

[Fedora (fedora-redhat-bugs)]

This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 21 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

[Fabio (fabio-redhat-bugs)]

This bug has not popped up in a while. So, I assume this has been fixed. Closing.
