I managed to get my own kernel compiled, the issue was that I did not have a console argument specified that I needed (I founded it on another post here)

console=tty0

Needed to be added to my kernel command line args.

Hope this is useful to someone in the future!

Hello,

I am running UT 15.04 on a Nexus 5 (Hammerhead) and I am trying to start doing some kernel development (I want to get gadgetfs working properly) however I am running into some issues that I'd like to resolve before going further.

I have installed a custom kernel which I built from the following repository (branch ubp-5.1):

https://github.com/ubports/android_kernel_lge_hammerhead

I have built the kernel (no modifications) with the cyanogenmod_hammerhead_defconfig config options and successfully crafted a boot image to run on my target device.

However, when I boot into my new kernel, bluetooth and WiFi no longer work and I see that no drivers are loaded when I run lsmod.

Presumably there is some configuration option that I am missing in my kernel, has anyone experienced this or can anyone point me in the right direction?

I believe that this is relevant to the error that I am getting:
