[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Kleber Sacilotto de Souza (kleber-souza)]

Boot testing completed successfully.

[Devices Certification Bot (ce-certification-qa)]

Kernel deb testing completes, no regressions found. Ready for Updates. Results here: https://trello.com/c/gkWR2KnZ/2105-bionic-linux-image-4150-154-generic-4150-154161

[Stefan Bader (smb)]

The primary regression test areas are hinted or passed. Added some additional hinting outside that space. But overall RT looks to be RT complete.

[Stefan Bader (smb)]

Verification tests are done but one web-cam related change which is isolated to specific HW and was verified in 5.4 (and 5.11).

[Kleber Sacilotto de Souza (kleber-souza)]

This kernel is ready for release. Setting kernel-signoff as 'Fix Released'.
