Using zfsbootmenu breaks my laptop's touchpad (fixed) #347

Problem: using zfsbootmenu breaks the touchpad on my laptop (HP Omen 16 2022)

Symptoms: Booting via zfsbootmenu results in this 1 logged error: kernel: i2c_designware AMDI0010:03: Unknown Synopsys component type: 0xffffffff

This prevents i2c-designware-pci from attaching properly to the device and providing the interface that subsequently connects to the touchpad via the i2c_hid_acpi driver.

The touchpad does not work. Booting directly (via grub, USB live image, ...) the touchpad works.

Solution: For kernels with this driver built-in (not a module) - includes Arch. initcall_blacklist=dw_i2c_init_driver,dw_i2c_driver_init needs to be added to the zbm kernel options that are set using efibootmgr

For kernels where the designware i2c driver is a module use (untested!!): i2c_designware_pci.blacklist=yes needs to be added

A user-editable Wiki to help collect small things like this is probably called for. I'll try to get a basic page outline created for this.

Closing because this is a client-side configuration issue. Setting the right KCL with efibootmgr, rEFInd or other intermediate loader, or editing the embedded KCL with zbm-efi-kcl will accomplish what you need.

I've added a very basic initial wiki page at https://github.com/zbm-dev/zfsbootmenu/wiki/Fixes-for-specific-hardware . Feel free to modify the layout if you're so inclined.
