Same problem on a Core i7 2600 (Sandy Bridge) with 3.20180312.0~ubuntu16.04.1.
Adding dis_ucode_ldr to grub's kernel command line temporarily (see /usr/share/doc/intel-microcode/README.Debian.gz) let me boot again, so I can try to download the older package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760264 Title: New version of intel-microcode freezes computer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1760264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
