The jammy task of this bug is marked as invalid, but the test plan is
asking to install the dkms package in jammy. Mistake, and you meant
noble?

Bug description:
[SRU Justification]
[Impact]
Outdated ACPI ID used in previous revisions, and the production one is
finally supported in a recent upstream WW3224-USBIO-PV-HFIX1 release.
[Fix]
https://github.com/intel/usbio-
drivers/commit/fc527affa4654468cdb63f8803eacd1a71b02017
[Test Case]
Install the built dkms binary package and linux-headers-generic-
hwe-22.04/jammy. The dkms build should be triggered and complete
successfully, and the devices with BIOS of 69W or a newer version
should work as usual.
[Where problems could occur]
It appears the i2c protocol meant to be governed by this usbio is not
in well control by the upstream collaborative peers, such that we fell
into various problems due the the mismatch of firmware version, and
therefore some ugly patch from Intel was added to work-around that.
While we don't have too much details about the design and the
solution, all we can do is to deploy extensive tests as possible.
[Other Info]
While linux-hwe-6.8 uses usbio-drivers/noble, the nominated candidates
are Oracular and Noble.
========== kernel SRU ==========
[Impact]
ov08x40 camera sensor is not working on IPU6 platforms.
[Fix]
A few changes from upstream kernel as well as a not yet upstreamed patch in
the Intel ipu6-drivers GitHub repo.
* commit b1a42fde ("media: ov08x40: Avoid sensor probing in D0 state")
* commit eea8f730 ("media: ov08x40: Modify the tline calculation in different
modes")
*
https://github.com/intel/ipu6-drivers/blob/Release_20240624/patch/v6.8/0001-media-ov08x40-Add-Tline-calculation-and-handshake-pi.patch
[Test Case]
The proposed kernel should have been built along with the updated
ipu6-drivers dkms. To verify ipu6-drivers alone, one will need
experimental kernels from https://launchpad.net/~canonical-hwe-
team/+archive/ubuntu/intermediate-kernel.
Here are steps for verifying kernels from -proposed pocket:
1. test camera after rebooting into a proposed kernel,
2. run suspend/resume stress test plan.
3. verify camera still working
[Where problems could occur]
These fixes are quite limited to ipu6/ivsc platforms, and affected no
power-consumption or other noticible problem.
[Other Info]
The fixing commits/patches were meant for in-tree driver, but yet it
changes device power up sequence and may affect platforms not
interested in IPU6 enablement. It is then duplicated into ipu6-drivers
dkms to avoid any unexpected side effect.
While some of the fixes are still under upstream review, meaning
they're not yet available in any kernel release, linux-
unstable/oracular/noble and oem-6.8/6.1x will be nominated for a
rebuild against new dkms.
