I can reproduce the same issue on a Lenovo ThinkPad X9 with Ubuntu 26.04. My Launchpad bug is: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2155194
System: - Laptop: Lenovo ThinkPad X9 / Lenovo 21QA0035US - OS: Ubuntu 26.04 LTS resolute - Kernel: 7.0.0-22-generic - IPU hardware: Intel Lunar Lake IPU7 - Sensor detected: SONY471A:00 / Sony IMX471 - libcamera: 0.7.0 Symptoms: - No /dev/video* devices are created - cam --list shows no available cameras - Chrome/WhatsApp/Camera apps cannot detect the internal webcam ubuntu-drivers detects the device and lists intel-ipu7-dkms: == /sys/devices/pci0000:00/0000:00:05.0 == modalias : pci:v00008086d0000645Dsv000017AAsd0000233Cbc04sc80i00 vendor : Intel Corporation model : Lunar Lake IPU manual_install: True driver : intel-ipu7-dkms - distro free I installed intel-ipu7-dkms: intel-ipu7-dkms: Installed: 0~git202602091007.a88b1909-0ubuntu1 Candidate: 0~git202602091007.a88b1909-0ubuntu1 dkms status shows: ipu7-drivers/0~git202602091007.a88b1909, 7.0.0-22-generic, x86_64: installed (Differences between built and installed modules) I also tried forcing DKMS installation: sudo dkms install -m ipu7-drivers -v 0~git202602091007.a88b1909 -k $(uname -r) --force sudo depmod -a sudo reboot After reboot, the system still loads the in-tree intel_ipu7 module: modinfo intel_ipu7 | grep -E "filename|intree|vermagic" filename: /lib/modules/7.0.0-22-generic/kernel/drivers/staging/media/ipu7/intel-ipu7.ko.zst intree: Y vermagic: 7.0.0-22-generic SMP preempt mod_unload modversions The dmesg error is the same: intel-ipu7 0000:00:05.0: Found supported sensor SONY471A:00 sysfs: cannot create duplicate filename '/kernel/software_nodes/SONY471A-0' kobject: kobject_add_internal failed for SONY471A-0 with -EEXIST intel-ipu7 0000:00:05.0: error -EEXIST: IPU bridge init failed intel-ipu7 0000:00:05.0: probe with driver intel-ipu7 failed with error -17 So this appears to be the same duplicate software node issue for SONY471A/IMX471 on Intel IPU7 platforms. Please let me know if I should attach any additional logs from my machine. ** Attachment added: "dmesg-ipu7-thinkpad-x9-14.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2158540/+attachment/5979901/+files/dmesg-ipu7-thinkpad-x9-14.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2158540 Title: ThinkPad X9-15 Gen 1: IPU7 camera probe fails — duplicate software_node SONY471A-0 (-EEXIST), bridge init failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2158540/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
