Comment 42 for bug 1933301

Jammy will release a few months later and we are aware of the development activities of Jammy 5.15 kernel. The patch needs to land Jammy as well to prevent user's dist-upgrade regression.

My investigation of the patch, 183b60e00597 crypto: hisilicon/qm - modify the uacce mode check, has clean cherry-pick with Jammy 5.15 master-next, and fixes the issue[1].

Next:
Process to merge 183b60e00597 with Jammy 5.15 kernel along with impish 5.13 (for up-coming focal-hwe)

[1] Before applying the patch (master-next branch, 5.15.13):
