This bug is awaiting verification that the linux-lowlatency- hwe-6.11/6.11.0-1007.7~24.04.1 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-noble-linux- lowlatency-hwe-6.11' to 'verification-done-noble-linux-lowlatency- hwe-6.11'. If the problem still exists, change the tag 'verification- needed-noble-linux-lowlatency-hwe-6.11' to 'verification-failed-noble- linux-lowlatency-hwe-6.11'.
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.

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 notisible problem. [Other Info] 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 fix. ========== original bug report ========== With IVSC switched to in-tree driver since 6.8 kernels in bug 2061747, it's still suffering from various problems that blocks camera driver stack being loaded correctly.
