Upgrade from 4.9 to 4.10: Macbook Pro stuck at boot

hi everyone,

I'm using an early 2011 MacBook Pro with a EFI Stub kernel and dm-encrypted drive. As long as I stay with kernel 4.9.* everything works fine, but no 4.10.* kernel so far got me any further than the blank screen at the beginning of the boot process (if it was booting into OSX this is where the Apple logo would appear or, as ususal, the linux kernel should take over).

I think this is still before anything considering the harddrive is loaded. If I remove the new config and .efi file from the EFI partition and put the .old files back into place, everything is up and running again.

The CPU in this machine is an "Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz".

What has changed from linux 4.9.* to linux 4.10.* that might explain this behaviour using the exact same kernel config?

And what parts of the kernel config would be helpful?

Thanks in advance!

I use Sakakis's genup script or buildkernel script for kernel updates, so I assume, this is handled correctly (it has worked from kernel 4.4 through 4.9). As suggested by iamben in the #gentoo irc chat I tried compiling the kernel with built-in i915 module (the idea was to see where things go wrong), but this did not change anything.

So I assume something's wrong when the initramfs should take over the boot process.

Is there a way to find out what has changed with kernel 4.10 especially regarding EFI and initramfs stuff?
Was there a new menuconfig option added defaulting to a, in my case, wrong position?
Was an existing option changed, so my config does not do what it's supposed to do anymore?

PS: This is what my .config looks like https://paste.pound-python.org/show/BUi2gafyDrzt5ahYcGjC/
