Not a massive priority but doing my part to reduce e-waste :) On MacBook8,1 (Early 2015, 12" Retina), the internal keyboard and trackpad do not work after boot despite the applespi driver being loaded and the IOMMU fix (iommu/vt-d: Restore context entry setup order) being present in kernel 6.17. The touchpad does not appear in xinput list, though the keyboard device may partially initialize. Workaround: Adding spi_pxa2xx_pci, spi_pxa2xx_platform, and applespi to /etc/initramfs-tools/modules and rebuilding initramfs resolves the issue: sudo nano /etc/initramfs-tools/modules Add these lines: spi_pxa2xx_pci spi_pxa2xx_platform applespi sudo update-initramfs -u sudo reboot This suggests a timing/race condition where the SPI controller needs to be initialized before IOMMU finalizes device mappings.
