Looking at your journalctl -k output it looks like you never did the: sudo insmod intel_cvs.ko command from the workaround instructions. If everything is setup properly this should result in a line like this in the journactl -k / dmesg output: Oct 10 12:51:20 saturn kernel: Intel CVS driver i2c-INTC10E0:00: cvs_i2c_probe:Transfer of ownership success which is not in your logs. Note the workaround instructions where missing a note about secureboot needing to be disabled to load the out of tree kernel module. I've added new updated workaround instructions to bug 2413656 comment 2. If you've secureboot enabled and run the: sudo insmod intel_cvs.ko command then you should see the following in your kernel logs: de nov. 08 09:53:09 patufet kernel: Loading of unsigned module is rejected which is also not there. Hi Hans! Thank you so much for your reply and advise! I did followed all of the steps and I repeated that twice yesterday and again today just to be sure, but the camera is not working - libcamera applications continue to fall back to SimplePipeline and report: No sensor found for /dev/media0 I also do not see the expected messages in journalctl that are mentioned in this bug. When I run sudo insmod intel_cvs.ko I do not get Intel CVS driver i2c-INTC10E0:00: cvs_i2c_probe:Transfer of ownership success in the journalctl - I am not sure why. The secure boot is disabled - I restarted the laptop and running all of the above instructions have no effect. I am attaching another joutnalctl + a screenshot of the terminal where I ran again the commands today. I would apprecite any help here, as I don't understand why this is not working or what am I missing. Please let me know if there are specific debug flags or logs I should collect.

It looks like these errors are the problem: Dec 16 11:23:39 fedora kernel: Intel CVS driver i2c-INTC10DE:00: magic number in dev response not supported Dec 16 11:23:39 fedora kernel: Intel CVS driver i2c-INTC10DE:00: cvs_find_magic_num_support:Device protocol is 1.0 Dec 16 11:23:39 fedora kernel: Intel CVS driver i2c-INTC10DE:00: cvs_common_probe:set_host_identifier cmd failed Dec 16 11:23:39 fedora kernel: Intel CVS driver i2c-INTC10DE:00: probe with driver Intel CVS driver failed with error -5 I suggest that you file a bug report at the intel vision drivers git repository: https://github.com/intel/vision-drivers/issues Thank you Hans for your help!
