Try all of the following combinations of kernel boot parameters by editing them at the grub menu (https://wiki.ubuntu.com/Kernel/KernelBootParameters): mitigations=off dis_ucode_ldr mitigations=off dis_ucode_ldr mds=off (Only) if any of these combinations boot fine, try them again at least five times or until a boot fails. Take notes and finally report how often you tried them and how often they booted fine, and whether there was a failed boot for each of these combinations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829657 Title: Ubuntu 16.04 with kernel 4.4.0-148 hangs on boot on a ThinkPad L460 while 4.4.0-145 doesnt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1829657/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
