** Bug watch added: Linux Kernel Bug Tracker #108981 http://bugzilla.kernel.org/show_bug.cgi?id=108981
** Also affects: linux via http://bugzilla.kernel.org/show_bug.cgi?id=108981 Importance: Unknown Status: Unknown ** Description changed: 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 + 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 - I have also reported this bug upstream: - https://bugzilla.kernel.org/show_bug.cgi?id=108981 - Please let me know what other info would be helpful.
