This bug is awaiting verification that the linux-oem-5.17/5.17.0-1004.4 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.

[Test Case] Apply the fix and kernel should print a new info line: Passthrough IOMMU for integrated Intel IPU and IPU6 camera should continue to work without intel_iommu=off work-around. [Where problems could occur] No. That's what it should have been done. [Other Info] This only affects kernel >= 5.15, so only Jammy is nominated. Intel IPU6 driver has been proposed for Jammy for hwe-5.15 migration in bug 1955383 (https://lists.ubuntu.com/archives/kernel-team/2021-December/126749.html). The port for 5.17 unstable would be filed soon. Still under discussion. While there is no plan for Intel to upstream Intel IPU6 driver before kernel camera API is out, these extra prerequisite patches will only be staged in a separate patches folder in the upstream repository. ========== original bug description ========== Intel iommu was turned on by default in mainline build v5.15.5 or jammy -generic kernel 5.15.0-12.12.
