Public bug reported:
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 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
I have also reported this bug upstream:

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