Cyking, thank you for reporting this and helping make Ubuntu better.
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-X.Y-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-X.Y-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.
