Did this issue start happening after an update/upgrade? Was there a
kernel version where you were not having this particular problem? This
will help determine if the problem you are seeing is the result of a
regression, and when this regression was introduced.   If this is a
regression, we can perform a kernel bisect to identify the commit that
introduced the problem.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.14 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.
