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 v4.17 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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[David Bogner (davidbogner)]

Same issue on my Dell XPS 15.

4.15.0-43-generic

[olivierm38 (ojp-maillard)]

I have the same issue on my AMD PC after upgrading to 18.04. Before there was no such message. It doesn't look harmful any way (Ubuntu seems to work just fine for months now), just troubling.
