> I'm wondering if the recent Intel microcode updates and related kernel patches could be responsible? Can you tell us what CPU the system has?
And BINGO! This was my suspicion too, I found a way to disable microcode updates to verify this: WORKAROUND: disable intel microcode updates >From this bug: >https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1759920 1/ add the boot parameter: dis_ucode_ldr to /etc/default/grub 2/ update-grub Results: - linux-generic (4.15.0.50): - proceeds to boot (I see some dmesg output, modules loading; gets stuck on some err on loading i915 module, probably due to the lack of microcode and new HW?) - linux-generic-hwe (4.18): - not tested yet - linux-generic-hwe-edge (5.0): - boots without an error! OK :) I'll be attaching the apport report for the ubuntu kernel I'm now able to boot. @Simon, can you please test this workaround and verify this hits ASUS and confirms it blames intel-microcode? ** Tags added: third-party-packages wayland-session ** Description changed: Description: - my system gets stuck at "Booting, Loading initramfs" (the first 2 lines of booting, after grub) - does not even show the enter cryptsetup passphrase - affected kernels: # apt list --installed |grep linux-signed WARNING: apt does not have a stable CLI interface. Use with caution in scripts. linux-signed-generic/bionic-security,bionic-updates,now 4.15.0.50.52 amd64 [installed] linux-signed-generic-hwe-18.04/bionic-security,bionic-updates,now 4.18.0.20.70 amd64 [installed] linux-signed-generic-hwe-18.04-edge/bionic-security,bionic-updates,now 5.0.0.15.71 amd64 [installed] - the setup is not new, has been working perfectly before (about 7 days since my last restart?) System: - HW: ASUS Zenbook 14 UX433FN - Ubuntu 18.04, runing latest HWE, fully updated - grub(-pc), cryptsetup (crypttab entries for custom encrypted LUKS setup), Suspected/possible cause?: - recent intel-microcode package update - recent kernel package updates Steps taken: - tried to remove "splash quiet" from grub/kernel cmd line (also tried adding nosplash, noplymouth) - completely removed nvidia drivers (apt purge *nvidia*) - completely purged and reinstalled grub (grup-pc) - completely purged and reinstalled all kernels (headers, modules, image, ..) - toggle BIOS "fastboot" (now using OFF) - toggle UEFI SecureBoot (now using ON) - remove plymouth (apt remove *plymouth* , but the workaround is working with plymouth installed) Workaround: - so far, I'm only able to boot with non-Ubuntu kernel! (linux-image-liquorix-amd64) - which needs "splash" option ON - reinstall cryptsetup & update-grub (as suggested in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1829620/comments/10 ) I am not sure how to get you more debug info, as this setup has been working before, and it's a very eary boot-process bug, so I can't even access dmesg etc. EDIT: Hypothesis: Only affects ASUS with newer (Kaby lake) Intel CPU, intel-microcode --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 CurrentDesktop: KDE DistroRelease: KDE neon 18.04 InstallationDate: Installed on 2012-12-23 (2337 days ago) InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.1) Package: linux-hwe-edge (not installed) Tags: bionic wayland-session Uname: Linux 5.0.0-17.1-liquorix-amd64 x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm libvirtd lpadmin netdev plugdev sudo vboxusers video _MarkForUpload: True + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.6 + Architecture: amd64 + CurrentDesktop: KDE + DistroRelease: KDE neon 18.04 + InstallationDate: Installed on 2012-12-23 (2339 days ago) + InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.1) + Package: linux-hwe-edge + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 5.0.0-15.16~18.04.1-generic 5.0.6 + Tags: third-party-packages bionic wayland-session + Uname: Linux 5.0.0-15-generic x86_64 + UnreportableReason: Toto není oficiální KDE balík.
