Yes there is no difference with 4.5-rc5-wily. The last message after
loading the kernel and then switching to a framebuffer console is about
btrfs. Then nothing but reactions to USB devices plugged in and .. me
forcing it to reboot.

I am wondering if something inside the initrd changed, in Xenial? I can
remember booting 4.1 and 4.2 kernels successfully from the kernel-ppa
with wily, I only fell back an older kernels to avoid specific i915
troubles.

Title:
  Xenial kernels hang on boot

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I run 3.19.0-999-generic #201502092105 SMP on a clevo W740SU. I cannot use a newer kernel, I tried various 4.3 to 4.4 versions, all show a similar symptom. The newer kernels do not seem to execute the init process, at least there are no traces of systemd in the first few minutes. Then after about 8 minutes systemd messages appear. Before that the last kernel trace I can see is from btrfs. I could only makee screenshots of those startup failures.
