ubuntu-17.10-beta2-desktop-amd64.iso also crashes on loading the kernel. Giving in GRUB CLI the final boot command immediately freezes the computer.

Is somebody on this? Possibly all Surface Book users (maybe only those with the dedicated NVidia chip) can't use F27 live ISO atm. It would be helpful if we could at least work on some workaround (updated initrd with latest Intel ucode for instance).

Comment 5 Chatty 2017-10-29 06:14:16 UTC

The solution to this bug is very easy: I inserted intel_ucode.img (taken from archlinux-2017.10.01-x86_64.iso) as first initrd and rawhide booted up fine.

Comment 6 Chatty 2018-02-23 20:29:48 UTC

This bug has become obsolete as Microsoft has updated the UEFI and microcode to 0xc2 which no longer blocks system from booting.
