Canonical has reverted the recent Intel Microcode update for the Tiger Lake processor family for all supported Ubuntu Linux releases to address a regression causing boot failures on some Intel Tiger Lake systems. . New security vulnerabilities are affecting all Linux systems running certain Intel processors. On November 10th, Intel released a new Intel Microcode firmware for Linux systems, and new Linux kernel versions were made available as well to address these new flaws. As I reported the other day, Canonical was quick to patch the Intel Microcode packages in all of its supported Ubuntu releases, including Ubuntu 20.10, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 14.04 ESM, and also released new kernel versions. Unfortunately, the Intel Microcode update caused a regression on certain processors in the Intel Tiger Lake family CPUs, causing the system to not boot. Therefore, Canonical now reverted the Intel Microcode update to the previous version only for the Tiger Lake processor family.
