Using 19.10 for a long time. This week had 2 times issue: 1st time: last kernel 5.3.0-45 hanged on boot and on recovery: loading initial ramdisk (in recovery mode, 5.3.0-45) Somehow I managed to boot and after this worked properly
2nd time, today: the same behavior, 5.3.0-42 recovery too. Chrooted from rescue USB and upgraded 3 packages, one of them was something about microcode... here are my versions, but didn't help... slava@slava-Latitude-5500:~$ dpkg -l | grep microcode ii amd64-microcode 3.20191021.1+really3.20181128.1ubuntu2 amd64 Processor microcode firmware for AMD CPUs ii intel-microcode 3.20191115.1ubuntu0.19.10.2 amd64 Processor microcode firmware for Intel CPUs ii iucode-tool 2.3.1-1 amd64 Intel processor microcode tool After I found your comments before, I tried to plug in power cable to my Dell Lattitude 5500 and I managed to boot with a normal mode. This way I remembered I plugged in a cable the 1st time too before successful booting The laptop is based on intel -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853369 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/1853369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
