I can confirm this is also a problem on my Dell Inspiron 1520. It seems to only happen using the 4.8.0 kernel. Resume from hibernation fails while decompressing the hibernation image. The boot time is much longer than when I use the 4.4.0 kernel on my Xubuntu 16.10 installation. It seems the drm/i915 module has undergone some big changes between 4.4.0 and 4.8.0, and now is asking for non-existant firmware during update- initramfs operations.

System regularly hangs for 10 second intervals which is very noticeable in boot process. Cause seems to be the Intel GMA965 DRM support causing regular kernel warnings: WARNING: CPU: 0 PID: 1183 at /build/linux-JqzU2_/linux-4.8.0/drivers/gpu/drm/drm_irq.c:1224 drm_wait_one_vblank+0x1b6/0x1c0 [drm] The problem seems to start very early in the boot process, possible already in GRUB, definitely when the kernel image is first started. Workaround: Boot into Ubuntu recovery mode and then resume into graphical system. In this case the problem does not occur.
