I finally solved it by inserting intel-ucode.img (taken from archlinux-2017.10.01-x86_64.iso) as the first initrd in grub.cfg. This updates the microcode very early in the boot process. I tried this with the kernel delivered with Ubuntu 17.10 (4.13.0-generic). So updating linux-firmware is the resolution. This also solves this bug: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1724650
But I found that WiFi is unstable after like 10 mins it gets disconnected and does not see any network anymore. Time for another bug. And when I used a new kernel image (4.14-rc6) and insterted belonging modules into initrd then "(initramfs) unable to find a medium containing a live file system." Oh well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724657 Title: Boot freeze with Ubuntu 17.10 Live ISO on Surface Book To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
