HillClimber, thank you for taking the time to report this bug and trying
to help make Ubuntu better. However, the upstream kernel is not a
software package provided by the official Ubuntu repositories. Because
of this and as outlined in https://wiki.ubuntu.com/Kernel/MainlineBuilds
the Ubuntu project can not support or fix your particular bug. Please
report this bug to the provider of the software package. Thanks!

If you are interested in learning more about software repositories and

Title:
   XPS 15 (9550) Won't boot with 4.4

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Neither 4.4rc3 nor 4.3rc4 will boot on my Dell XPS 15 (9550).  4.3
  boots fine.

  The boot process halts with "ALERT! /dev/disk/by-uuid/<uuid> does not
  exist", although the UUID does exist, and other kernels boot fine.

  I'm attaching a screenshot of the console boot log.  I apologize that
  it is hard to read, because my screen is 3840x2160 and each line is
  less that 2mm high.

  Here's my grub stanza:

                  load_video
                  gfxmode $linux_gfx_mode
                  insmod gzio
                  if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
                  insmod part_gpt
                  insmod ext2
                  if [ x$feature_platform_search_hint = xy ]; then
                    search --no-floppy --fs-uuid --set=root  7e2ed448-28a7-465e-a5b0-58db19b2711a
                  else
                    search --no-floppy --fs-uuid --set=root 7e2ed448-28a7-465e-a5b0-58db19b2711a
                  fi
                  echo    'Loading Linux 4.4.0-040400rc4-generic ...'
                  linux   /boot/vmlinuz-4.4.0-040400rc4-generic root=UUID=7e2ed448-28a7-465e-a5b0-58db19b2711a ro  quiet splash i915.preliminary_hw_support=1 i915.enable_ips=0 $vt_handoff
                  echo    'Loading initial ramdisk ...'
                  initrd  /boot/initrd.img-4.4.0-040400rc4-generic

  Possibly related is the following warning when i update-initramfs:

  $ sudo update-initramfs -u
  update-initramfs: Generating /boot/initrd.img-4.4.0-040400rc4-generic
  W: Possible missing firmware /lib/firmware/i915/skl_guc_ver4.bin for module i915

  Please let me know what other info would be helpful.  Thanks!
