[Bug 1829620] Re: intel-microcode on ASUS makes kernel stuck during loading initramfs on bionic-updates, bionic-security

Is there a BIOS update for your Dell? I updated my Asus' BIOS and it fixed
the issue.
Though, now the NVIDIA driver does not work for me. I haven't had a chance
to dig in on yet. Perhaps a reinstall of the driver would fix it.

Title:
  intel-microcode on ASUS makes kernel stuck during loading initramfs on
  bionic-updates, bionic-security

Status in intel-microcode package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Confirmed
Status in linux-hwe package in Ubuntu:
  Confirmed
Status in linux-hwe-edge package in Ubuntu:
  Confirmed

Bug description:
  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 i7-8565U Whiskey Lake Intel CPU

  Upstream Bug Report:
  https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/1

  WORKAROUND 1: disable intel microcode updates during boot
  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

  WORKAROUND 2: downgrade (and hold) intel-microcode to older version from bionic/main
  apt install --reinstall intel-microcode=3.20180312.0~ubuntu18.04.1

  WORKAROUND 3: upgrade BIOS
  Asus has released updated BIOSes, which probably include the newest microcode. After upgrading workarounds 1,2 are not needed. 
  Please NOTE, unlike workarounds 1,2, BIOS upgrade is permanent and cannot be (easily) reverted.
