This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1882834

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Hello Team,

Thanks for the update. Could you confirm if above 6 patches are applied to Ubuntu kernel? If not can you please apply to ongoing ubuntu kernel release?

Along with those, could you help port the below patch too to the kernel where above patches are applied? The below one should be after the above 6 patches are applied.

Let me know if any concerns.
