Entry 24 is upstream's, added in 6.19. Entry 26 sits just before TBE20A0, apparently added by "SAUCE: media: ipu-bridge: add TBE20A0 ACPI id for Sony IMX471" (LP: #2138841). The second pass registers the same software node again, so bridge init fails. Fix: drop the duplicated SONY471A entry from the SAUCE patch and keep TBE20A0. --- ProblemType: Bug ApportVersion: 2.34.1-0ubuntu0.1 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 26.04 InstallationDate: Installed on 2026-06-07 (127 days ago) InstallationMedia: Ubuntu 26.04 "Resolute Raccoon" - Release amd64 (20260423.1) MachineType: LENOVO 21Q6CTO1WW Package: linux (not installed) ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcFB: 0 xedrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-7.0.0-38-generic root=UUID=b7d46262-4dad-4721-97f0-70eba2f7aa21 ro quiet splash crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M ProcVersionSignature: Ubuntu 7.0.0-38.38-generic 7.0.14 RebootRequiredPkgs: Error: path contained symlinks.
