Dell XPS5510 with i7-6820HQ has exactly the same issue on Ubuntu 19.10 after fresh install, apt-update && apt-upgrade && reboot, gives purple screen / stuck at Loading initramfs. Switching kernel works once but next reboot it's stuck again.
Update of BIOS via built in one time setup menu and USB stick seems to have solved the issue. Not working bios version was 5.2.something and working BIOS version is 1.13.1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829620 Title: intel-microcode on ASUS makes kernel stuck during loading initramfs on bionic-updates, bionic-security To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1829620/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
