Hello,

Following the guide at 
https://source.android.com/setup/build/building-kernels for the Pixel 3 
(blueline) will put you in the same situation; a bootable kernel, but 
without touchscreen (and I suspect other drivers, like audio) working:

$ repo init -u https://android.googlesource.com/kernel/manifest -b 
android-msm-crosshatch-4.9-pie-qpr2
$ repo sync
$ build/build.sh
$ adb reboot bootloader
$ fastboot boot out/dist/Image.lz4-dtb
$ # boots, but :(

> I suspect your device is missing the touch screen drivers (maybe the 
> drivers you have in your device are not compatible with your kernel). 

I find it odd that custom Pixel 3 kernels available on XDA (
https://forum.xda-developers.com) boot and work (fastboot boot ) 
with stock vendor modules, but the kernels generated from the build guide 
requires workarounds to move things to /vendor/lib/modules.

Would this mean that the guide is broken for Pixel 3 (blueline), that the 
*build/build.sh* script is not suitable for building stock vendor 
compatible kernels?
