@enr0n noticed jumps in time in dmesg that could cause this issue:

Title:
  systemd-modules-load fails on Azure 23.10 images on arm64

Status in cloud-images:
  New
Status in systemd package in Ubuntu:
  New

Bug description:
  On some arm64 instances systemd-modules-load.service fails with the
  following error:

  $ sudo journalctl -u systemd-modules-load
  Oct 04 08:03:30 ubuntu systemd[1]: systemd-modules-load.service: start operation timed out. Terminating.
  Oct 04 08:03:30 ubuntu systemd[1]: systemd-modules-load.service: Main process exited, code=killed, status=15/TERM
  Oct 04 08:03:30 ubuntu systemd[1]: systemd-modules-load.service: Failed with result 'timeout'.
  Oct 04 08:03:30 ubuntu systemd[1]: Failed to start systemd-modules-load.service - Load Kernel Modules.

  It only fails on boot, when restarted manually the service runs fine.
  I can't find which module fails to load. The only kernel module that
  this service is supposed to load is multipathd and it appears to be
  loaded even when the service has failed.
