I believe this system is using S0i3 for suspend, in case that's relevant. If I boot from power off, then the trackpad works fine in both the pre-boot BIOS and in Ubuntu 22.04 (prerelease), including haptic response to clicks. After a suspend/resume cycle, the trackpad stops responding, although a lot of swiping/pressing will occasionally produce a button press event. This state persists even if I reboot out of Linux (without a power cycle) - for example the trackpad no longer works for the pre-boot BIOS configuration screen, until a full power cycle (which fixes the trackpad). Possibly relevant, the trackpad seems to be this device to the kernel: [ 2.016917] input: SNSL0001:00 2C2F:0006 Mouse as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-1/i2c-SNSL0001:00/0018:2C2F:0006.0001/input/input6 [ 2.016964] input: SNSL0001:00 2C2F:0006 Touchpad as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-1/i2c-SNSL0001:00/0018:2C2F:0006.0001/input/input7 [ 2.017027] hid-generic 0018:2C2F:0006.0001: input,hidraw0: I2C HID v1.00 Mouse [SNSL0001:00 2C2F:0006] on i2c-SNSL0001:00 and the last kernel messages before suspend are: [ 305.216189] Freezing remaining freezable tasks ...
