Not boot with EFI

Please test this kernel and tell us if it solves you problem:

https://people.canonical.com/~ppisati/lp1827750/

This kernel has EFI support (and several other EFI features) enabled:

https://git.launchpad.net/~p-pisati/ubuntu/+source/linux/commit/?h=b-raspi2-lp1827750&id=ce621b56138a15dd3c67d6b40429f5739a6b51ec

Once positively verified, add a step by step test procedure to this bug so we can move forward with integrating the changes.

Dependency error of linux-headers-4.15.0-1035-raspi2 package. This is required itself.

dpkg: package dependencies do not allow configuring the linux-headers-4.15.0-1035-raspi2 package:
  linux-headers-4.15.0-1035-raspi2 depends on linux-raspi2-headers-4.15.0-1035, however:
   The linux-raspi2-headers-4.15.0-1035 package is not installed.

Copied out that package, try again.

System started, but I can't parse temperature. CPU freq info work fine.

cat: /sys/class/thermal/thermal_zone0/temp: No such file or directory

FYI the mainline arm64 kernels at https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1.1/ boot on the 3B running arm64 on disco, with grub-efi-arm64-bin installed and a commandline of modprobe.blacklist=vc,vc4 (but I haven't tried without using the module blacklist for some time.)

Since the default RPI bootloader doesn't seem to handle kernels with an EFI stub though, enabling the EFI stub will cause boot problems on kernels using the built-in RPI bootloader, no?

Take care, current kernel 4.15.0-1036.38 still not bootable with EFI.
