** Description changed: I don't know if this is a problem with the kernel or the microcode, but we have a significant number of computers in our organization (on both 16.04 and 17.10) that fail if they have both updated. Booting with either linux-image-4.13.0-36-generic or intel-microcode 3.20180108.0+really20170707ubuntu17.10.1 allows all these computers to boot. + + ## Workaround ## + 1. Boot the system with the dis_ucode_ldr kernel boot parameter to temporary avoid the problem: + https://wiki.ubuntu.com/Kernel/KernelBootParameters + 2. Install the previous version of package from + https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/14261530/+files/intel-microcode_3.20180108.0+really20170707ubuntu16.04.1_amd64.deb + 3. (Optional) Hold the package so that it won't be upgraded accidentally + sudo apt-mark hold intel-microcode
