Title:
System freeze during starup on activation of systemd device unit for
EFI system partition by label with kernel 6.14

Status in linux package in Ubuntu:
Expired

Bug description:
Since upgrading the HWE kernel from version 6.11.0-29.29~24.04.1 to 6.14.0-27.27~24.04.1 on Ubuntu 24.04 I am observing freezes during startup on activation of the systemd device unit for the EFI system partition by label (dev-disk-by\x2dlabel-MKFS_ESP.device).
Masking this unit makes startups sporadically succeed, but not consistently.
Ubuntu mainline build versions 6.13.12, 6.15.8 and 6.16.0 seem to work fine, but version 6.14.11 exhibits the same fault.

Since the system freezes early in the startup sequence the logs do not
appear in the previous boots of the journal. It is therfore difficult
to provide more detailed information about the exact fault.

I am currently only attaching the output of lspci as a start. Please
feel free to request more information and I will try to provide it.
