Regression summary Hardware: - Intel IPU6 platform - OV02E10 camera sensor (ACPI device OVTI02E1:00)
Regression window: - Working kernel: 6.14.x - Failing kernels: 6.17.x and 7.0.0-28-generic Symptoms: - Internal MIPI camera no longer detected - cam -l reports no cameras - Sensor is missing from media topology Relevant observations: IPU6 is detected successfully: intel-ipu6 0000:00:05.0: Found supported sensor OVTI02E1:00 intel-ipu6 0000:00:05.0: Connected 1 cameras The camera sensor probe subsequently fails: ov02e10 i2c-OVTI02E1:00: failed to write reg 253 val 0 ov02e10 i2c-OVTI02E1:00: failed to find sensor: -5 ov02e10 i2c-OVTI02E1:00: probe with driver ov02e10 failed with error -5 INT3472 messages during boot: int3472-discrete INT3472:01: cannot find GPIO chip INTC10D1:00, deferring int3472-discrete INT3472:0c: cannot find GPIO chip INTC10D1:00, deferring Additional findings: - ACPI device INTC10D1:00 exists - GPIO chip labelled INTC10D1:00 is present - intel_skl_int3472_discrete and intel_skl_int3472_tps68470 modules are loaded - intel_ipu6, intel_ipu6_isys and intel_ipu6_psys modules are loaded - media-ctl shows the IPU6 topology but no OV02E10 sensor entity - libcamera reports "Available cameras:" with none listed This appears to be a kernel regression in the OV02E10 / INT3472 / IPU6 camera initialization path introduced between 6.14 and 6.17. ** Tags added: kernel-regression ** Tags added: camera intel ipu6 mipi ov02e10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2162099 Title: [REGRESSION] OV02E10 sensor probe failure on Intel IPU6 after 6.14, fails on 6.17 and 7.0 kernels Show more lines To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2162099/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
