After upgrading my BIOS the problem came back again with the 4.15 kernels. I was able to solve the issue by adding noapic to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default grub, e.g.:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic" Once I did that, the kernels worked fine as did intel-microcode. I'll update the description and details of the ticket to reflect my findings. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1751584 Title: Ubuntu doesn't boot with 4.13.0 kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1751584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
