[Bug 1829657] Re: Ubuntu 16.04 with kernel 4.4.0-148 hangs on boot on a ThinkPad L460 while 4.4.0-145 doesnt
I had same problem on ThinkPad 13 with Kubuntu 16.04. Adding dis_ucode_ldr as a kernel boot parameter solved the problem.

@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

Same issue here, Thinkpad L460, Lubuntu 16.04, affected kernels 4.4.0-148 and 4.4.0-150, same screenshot as Max P.

Diederik: Ubuntu 14.04 reached end of life, is no longer supported. Max, and anyone else affected by this issue with identical symptoms as Max on Ubuntu 16.04 with kernel 4.4.0-148, please consider testing this: 1. Add this to /etc/default/grub : GRUB_GFXPAYLOAD_LINUX="text" 2. Add this to the GRUB_CMDLINE_LINUX_DEFAULT option in /etc/default/grub : earlyprintk=efi,keep 3. Run: sudo update-grub 4. 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
