@Tom Reynolds, when I use dis_ucode_ldr as a kernel boot parameter, booting and shutdown work fine. Whether or not I also add mitigations=off or mds=off does not matter. Tested five times with 4.4.0-154.
The older kernel 4.4.0-146 boots fine without special parameters, but hangs on shutdown. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
