I have a strange issue with the newest kernel
4.9.0-5-amd64 on this 2011 Macbook Pro.
As far as I can see it has to do with the power management of this laptop.
Whenever the laptop is on power supply the boot process stops hard after
I enter the passphrase for the encrypted lvm. There is one last message
that it tries to mount root but it stops hard there. There is also no log

when I unplug the laptop during boot it boots fine.
Previous kernel do not show this behavior.
