Title:
  broken initrd.img after upgrade to 24.04

Status in initramfs-tools package in Ubuntu:
  New
Status in linux package in Debian:
  Confirmed

Bug description:
  I had to upgrade a system from 22.04 to 24.04. So far, so good. Only
  after the reboot I realized I was unable to start the system.
  Debugging it was very cumbersome because it was over a slow link
  including character duplication issues when typing.

  Anyways, I tried to dig into it after a reinstall, and found that the
  initrd.img got regenerated (which also led to being unable to boot
  into the old kernel, not just the new one of 24.04). So another
  reinstall later I made sure to copy away the working initrd.img from
  22.04, and compare it to the one (re)generated by 24.04. It contained
  about 500 less lines in the output of lsinitramfs.

  The system contains hardware raid. grub is able to see the disks, only
  the (broken) initrd.img isn't able to see the disks anymore. blkid
  gives no output at all in the shell I'm dropped into.

  The server is needed for production purposes, so I had reinstalled
  once again to 22.04 to continue working. I have copied off both of the
  initrd.img files for the 5.15.0-118-generic kernel, both the one that
  was generated for 22.04, and the one that was re-generated in the
  upgrade process to 24.04.

  If you need more information, please let me know.
