** Description changed:
+ SRU Justification:
+
+ [Impact]
+
+ In bug 2138721, a temporary work-around was proposed by Intel, and a
+ latter formal release with ABI breakage fixed is then available as
+ linux-firmware commit e2207455 ("Intel IPU7: Update firmware binary for
+ Panther Lake").
+
+ [Fix]
+
+ 1. ipu7-drivers upstream tag release 20260129_1800_11 is used, along
+ with additional fixes to address the build time/runtime issues
+ completely.
+
+ 2. linux-firmware updates are required, too. For Resolute, revert the
+ change for bug 2138721 as commit e2207455 is in linux-firmware/resolute
+ since version 20260123.git1b7b9f6c-0ubuntu1. For Noble, revert the
+ change for bug 2138721 and cherry pick commit e2207455.
+
+ 3. For kernels, update dkms-versions.
+
+ [Test Plan]
+
+ 1. install dkms and linux-firmware from -proposed pocket. It should
+ automatically trigger dkms kernel modules build for current running
+ kernel.
+
+ 2. Reboot and test if camera function works as usual.
+
+ [Where problems could occur]
+
+ Firmware updates, opaque to the public.
+
+ [Other Info]
+
+ While bug 2138721 applies to N and R so far, nominate fixes for N and R
+ as well.
