Sure, but there is plenty of space at /boot and / (and I would have noticed some "insufficient disk space" if that happened during initrd creation).

Status in linux package in Ubuntu: Confirmed Bug description: I am using Ubuntu 24.04.1 LTS. After the upgrade to kernel 6.8.0-47 from 6.8.0-45, for the first time, Ubuntu was unable to recognize my ethernet, wifi and bluetooth. None of these issues occurred before since they were automatically recognized and configured by the installer. The only solution I found was to revert to 6.8.0-45.
