IPU6 camera has no function on Andrews MLK

Removed linux-firmware from affected packages. No extra firmware needed, no existing firmware being updated. ipu6ep is still used.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1964983

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This bug is awaiting verification that the linux-oem-5.14/5.14.0-1032.35 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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!

Using kernel 5.14.0-1032-oem, the camera sensor and ipu6 driver was working correctly. I can get camera working with userspace stack in ppa:oem-solutions-engineers/intel-ipu6.

This bug was fixed in the package linux-oem-5.14 - 5.14.0-1032.35

Patches reverted in jammy due to regression.

To switch to dkms since oem-5.17.

Regarding 5.15.0-40-generic in jammy-proposed, Call Trace will always happen when the first time to use the webcam by https://webcamtests.com/.
But the functionality seems to be just fine on Dell Latitude 9420.
