[Bug 2133825] Re: intel-usbio-dkms FTBS in Noble with the linux-6.17-hwe kernel

[Timo Aaltonen]

Hello John, or anyone else affected,

Accepted usbio-drivers into noble-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/usbio-
drivers/0~git202312141918.78ffb706-0ubuntu2.2 in a few hours, and then
in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: usbio-drivers (Ubuntu Noble)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-noble

  [ Test case ]

  Install the latest linux-6.17 kernel on Noble:

  $ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
  $ sudo apt install linux-generic-hwe-24.04-edge

  Install intel-usbio-dkms:

  $ sudo apt install intel-usbio-dkms

  Module build and installed successfully.

  Load the modules:

  $ sudo modprobe usbio
  $ sudo modprobe i2c-usbio
  $ sudo modprobe gpio-usbio

  Modules loaded successfully.

  The same procedure must be repeated on linux-6.8 to test for possible
  regressions.

  [ Fix ]

  Apply patches from intel-usbio-dkms from Questing release:

  * debian/patches/backport-fix-build-against-kernel-6.17.patch

  Adding dh-dkms to build dependencies

  [ Regression potential ]

  We may experience regressions in systems that are using the usbio-
  drivers, especially with kernels >= 6.8 kernel.
