RPi2 image of Second Snappy Ubuntu Core 15.04 stable release now available!

[Víctor Mayoral Vilches]

Thanks for putting time into this. I've spent some time trying to reproduce
your work with the aim of having a custom kernel on the Snappy image for
the RPi2.

My approach has been:

   - Tried compiling the kernel from
   http://kernel.ubuntu.com/git/ubuntu/ubuntu-vivid.git/
   - Config (fetched from the Snappy image from the pi itself)
   https://github.com/vmayoral/ubuntu-vivid/blob/6048e721da04db6fe5e024166bb5e65aa57b8b90/arch/arm/configs/config-3.19.0-23-generic_hacked_defconfig
   after removing the CONFIG_STRICT_DEVMEM=y option.
   - Replaced the kernel (vmlinuz) in the appropriate partition.


The result is that the kernel does not boot. Gets stuck at
https://gist.github.com/vmayoral/5c99fe85fbfc284740fd. Am i using the right
tree? Any tips on how to recreate the kernel Oliver included on the last
image?

Thanks,
