Hi Krystian, You're right — I checked further and CONFIG_PINCTRL_AMD=y is indeed built into the kernel, and the driver functions are present and active:
$ cat /boot/config-7.0.0-28-generic | grep PINCTRL_AMD CONFIG_PINCTRL_AMD=y CONFIG_PINCTRL_AMDISP=m $ sudo grep -E 'amd_gpio_(probe|driver|irq_handler)' /proc/kallsyms ffffffffb19e4ea0 t amd_gpio_probe ffffffffb39414e0 t amd_gpio_driver ffffffffb19e39b0 t amd_gpio_irq_handler (and related symbols) So my earlier assumption about a missing pinctrl_amd module was wrong (I had tested modprobe pinctrl_amd, but since it's built-in rather than a loadable module, that test wasn't valid). Given the driver is present and active, the issue seems to be elsewhere — possibly in how the ACPI tables describe the interrupt routing for the ELAN0718 device specifically, since i2c_hid_acpi never even attempts to probe it (no related lines in dmesg at all, unlike the Arch thread I referenced earlier where at least a probe with error -22 was logged). Happy to run any further diagnostics you'd like. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161223 Title: Touchpad (ELAN0718) not working on HP Pavilion Gaming Laptop 15 with kernel 7.0.0 (Ubuntu 26.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161223/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
