Item didn't make it in time for jammy / 22.04, therefore we need to move this to Ubuntu 22.10.

This bug is awaiting verification that the linux-hwe-5.19/5.19.0-24.25~22.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Initial bug was reported just for jammy.
So to unblock the process I'm marking this as verification-done.
