Updated to 6.17.0-14-generic -> No luck here :(
6.17.0-16-generic on proposed -> No luck either :(
** Description changed:
Heya folks,
I know, really old macbook. 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.
