Same issue on Dell Pro 14 Premium PA14250 (Lunar Lake, Core Ultra 7 266V) with OV08F40 sensor (ACPI: OVTI08F4:00) on both Ubuntu 24.04 and 26.04.
Kernel log: int3472-discrete INT3472:00: GPIO type 0x02 unknown; the sensor may not work This affects multiple Dell models across BOTH Meteor Lake and Lunar Lake: - Dell Pro 14 Premium PA14250 (Lunar Lake, IPU7) — my hardware - Dell Pro Plus 14 PB14250 (Lunar Lake, IPU7) - Dell Pro Max 14 MA14250 (Meteor Lake, IPU6) — GitHub issue #417 - Dell 16 Premium DA16250 (Meteor Lake, IPU6) — this bug I have manually patched INT3472 to handle GPIO type 0x02 on Ubuntu 26.04 and confirmed it resolves the warning. The sensor is detected: intel-ipu7 0000:00:05.0: Found supported sensor OVTI08F4:00 intel-ipu7 0000:00:05.0: Connected 1 cameras Marco Nenciarini's STROBE patch series (now at v8) has been under review on platform-driver-x86 mailing list since March 2026 but is still not merged. Andy Shevchenko and Hans de Goede have both reviewed it. Additionally, the Dell OEM archive for Ubuntu 26.04 (resolute-somerville) has not been published — 15 days after release. libcamhal0 is unavailable.

This single 3-line kernel change unblocks camera on ALL affected models. ** Bug watch added: github.com/intel/ipu7-drivers/issues #26 https://github.com/intel/ipu7-drivers/issues/26 ** Bug watch added: github.com/intel/ipu6-drivers/issues #417 https://github.com/intel/ipu6-drivers/issues/417 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2138991 Title: Dell 16 Premium DA16250 webcam (OV02C10) not working - INT3472 GPIO type 0x02 unknown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ipu6-drivers/+bug/2138991/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
