Assuming you can at least get it to boot, I'd recommend either: a) Manually download and install the version of intel-microcode from Ubuntu 16.04: http://packages.ubuntu.com/xenial/intel-microcode b) Follow the Linux instructions here: https://github.com/bgw/bdw-ucode-update-tool Normally, I wouldn't recommend installing Ubuntu 16.04 packages on Ubuntu 15.10, but intel-microcode is just some firmware, shell scripts, and configuration files, so it should be pretty safe. -- You are receiving this mail because: You are the assignee for the bug.
