A recent update seems to have triggered this behaviour for me also. I'm using a Thinkpad X260 with an i3-6100U running 20.04.
After going from intel-microcode:amd64 3.20200609.0ubuntu0.20.04.2 to 3.20201110.0ubuntu0.20.04.2 I am unable to boot my machine normally, with the boot process hanging on the "Loading initial ramdisk" message. I have 3 kernel versions available at boot, all of which appear equally broken - 5.4.0.52-generic - 5.4.0.53-generic - 5.4.0.54-generic However I am able to boot if I manually edit the grub entry to include the `dis_ucode_ldr` parameter... Let me know if my comment should be moved somewhere else or if you need any more information. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858810 Title: [19.10] Boot hangs at "loading initial ramdisk" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1858810/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
