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

Kernel deb testing completes, no regressions found. Ready for Updates. Results here: https://trello.com/c/gCHtivqG/2320-bionic-linux-image-4150-163-generic-4150-163171

[Kleber Sacilotto de Souza (kleber-souza)]

Regression tests completed successfully.

[Stefan Bader (smb)]

There is only one bug report unverified and that is security related and was part of stable on at least hirsute. So I think it is valid to accept this without explicit verification.

[Stefan Bader (smb)]

To my knowledge this looks to be good to release.
