[Bug 2061747] Autopkgtest regression report (linux-meta/6.8.0-32.32)

[Ubuntu SRU Bot]

All autopkgtests for the newly accepted linux-meta (6.8.0-32.32) for noble have finished running.
The following regressions have been reported in tests triggered by the package:

cryptsetup/unknown (arm64)
dropbear/2022.83-4 (arm64)
dropbear/unknown (armhf)
zfs-linux/2.2.2-0ubuntu9 (arm64)


Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

  ========== linux-meta, linux-meta-unstable, linux-meta-oem-6.8
  ==========

  [Impact]

  Starting from kernel v6.8, Intel demands the use of in-tree VSC driver
  instead of the out-of-tree dkms originated from
  https://github.com/intel/ivsc-driver.

  [Fix]

  The main fixes are in kernel & dkms packages. This adds ivsc-modules to
  Provides list of linux-image-generic as other built-in linux-modules-foo
  packages do.

  [Test Case]

  The generated meta package linux-image-generic should then provides
  "ivsc-modules".

  [Where problems could occur]

  Meta package changes only. No real effect but in package dependency.

  [Other Info]

  While the ivsc-dkms obsoletion only happens for kernel >= 6.8, this will
  only be nominated for Unstable/Noble/OEM-6.8.

  ========== ipu6-drivers, linux, linux-oem-6.8 ==========

  [Impact]

  Starting from kernel v6.8, Intel demands the use of in-tree VSC driver
  instead of the out-of-tree dkms originated from
  https://github.com/intel/ivsc-driver.

  [Fix]

  The in-tree vsc driver as of v6.8 still needs a few fixes to achieve
  the same support level to launch Intel IPU6 Camera devices. Commit
  1,3, and 4 are to add supported devices and platforms. Commit 2
  resolves an issue after resumed.

  [Test Case]

  This is supposed to work together with the updated dkms, which shall
  also be built along with the kernel itself as linux-modules-
  ipu6-<variant>. Install the corresponding kernel/modules packages and
  test camera functions.

  [Where problems could occur]

  While this is the first time we switch to in-tree VSC driver, and the
  out-of-tree driver is not aligned at the time of transition and
  probably never will, the provided functions and verified stability
  issues may vary.

  [Other Info]

  The dkms is created to be compatible of multiple kernel versions, yet
  the in-tree vsc driver transitioning should only happen for kernel >=
  v6.8. That is, oem-6.8, noble and linux-unstable will be nominated.

  ========== original bug description ==========

  Starting from kernel v6.8 (yet from the code diff it's v6.6), Intel
  demands the use of in-tree IVSC drivers instead of out-of-tree dkms
  from https://github.com/intel/ivsc-driver.
