I am posting my updates on askubuntu.com also: https://askubuntu.com/questions/1243328/dual-boot-windows-10-ubuntu-linux-18-04-lts-upgrade-to-20-04lts-kernel-5-4-is
I tried installing various other kernels thinking that it might fix this problem but no luck. Mine is Dell XPS 8930 Desktop so I don't power cable should be an issue for laptops. Recently my other Dell XPS laptop got a BIOS update. It is running Windows 10 dual boot with Ubuntu 18.04 LTS - I am not going to upgrade ubuntu due to this issue. ** Attachment added: "tried other kernels also" https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1853369/+attachment/5391687/+files/Selection_162.png -- 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
