5.19.0-45-generic stalls on boot

[Adam Jones]

Version: Ubuntu 22.04.2 LTS

After installing the `5.19.0-45-generic kernel`, my system no longer boots properly. Going via GRUB and starting either `5.19.0-45-generic kernel (recovery)` (and then choosing 'resume') or `5.19.0-43-generic kernel` works correctly. I didn't intentionally update this part of my system, I think it was just part of a regular `sudo apt update` and `sudo apt upgrade`.

I can't seem to find the logs for any of the failed boots in journalctl. Happy to take advice on what logs need to be provided (but please be detailed on how I can retrieve them e.g. by providing links to documentation I should follow).

Expected behaviour:
- The system shows the BIOS splash screen, then goes black for a second, then shows the motherboard brand logo (but without any bios keys etc.) for a second, then shows the encryption dialog. After entering encryption password, the system boots into the desktop.

Actual behaviour:
- Normal boot: The system shows the BIOS splash screen, then goes black for a second, then shows the motherboard brand logo (but without any bios keys etc.). It then seems to just be stuck here (waited 15 minutes and no change).
- Grub boot: The system shows the BIOS splash screen, then goes black for a second, then opens GRUB. Based on selection here:
  - Ubuntu: the system shows the motherbroad brand logo and gets stuck.
  - Advanced > 5.19.0-45-generic kernel: the system shows the motherbroad brand logo and gets stuck.
  - Advanced > 5.19.0-45-generic kernel (recovery): the system boots into recovery just fine, and prompts me for the encryption password along the way. Using 'resume' here loads the desktop and things appear to work as normal.
  - Advanced > 5.19.0-43-generic kernel: the system shows shows the motherboard brand logo (but without any bios keys etc.) for a second, then shows the encryption dialog. After entering encryption password, the password field gets stuck.
  - Advanced > 5.19.0-43-generic kernel (recovery): same as 5.19.0-45-generic kernel (recovery)

Other troubleshooting context:
- I have full-disk encryption enabled
- The system appeared to be working fine before these updates
- I have an Intel CPU and Nvidia GPU

It appears others might be experiencing this bug, with some discussion on AskUbuntu https://askubuntu.com/questions/1473252/someone-else-experienced-boot-failures-with-the-5-19-0-45-generic-kernel-version

Following the instructions on debugging kernel boot problems ( https://wiki.ubuntu.com/DebuggingKernelBoot ), I think I've found a workaround and perhaps a clue as to where the problem lies.

Workaround:
  Disable Intel graphics in your BIOS. For me, this was in Peripherals > Intel Processor Graphics > Set to 'Disabled'

Key log:
  i915 0000:00:02.0: enabling device (0006 -> 0007)
