System hangs for 1:30 minute on /dev/disks/by-designator/esp

Hi Lachu,

I ran into the same error after zypper dup.

In the end, the cause turned out to be the following: the LoaderDevicePartUUID variable was missing from efivars.

  • The EFI entry openSUSE Boot Manager pointed to:

EFI\SYSTEMD\SHIM.EFI

  • shim launched the same SYSTEMD-BOOTX64.EFI, but without the correct systemd-boot EFI variables context;
  • sysefi-generator in the initrd could not find LoaderDevicePartUUID;
  • a fallback was selected: /dev/disk/by-designator/esp;
  • this caused a conflict between services, and one of the services was disabled after a timeout. After that, the boot process continued normally.

After upgrading to the newer systemd version during the latest update, this became an issue. With the previous version, everything worked as expected.

Please check:

ls /sys/firmware/efi/efivars | grep LoaderDevice

In the end, I ran:

sudo bootctl install

As a result, I got another boot menu entry:

Boot0002 Linux Boot Manager

It directly loads:

EFI\SYSTEMD\SYSTEMD-BOOTX64.EFI

and should work correctly.

Now the normal boot path goes through this chain:

UEFI
└─ Boot0002
----└─ EFI\SYSTEMD\SYSTEMD-BOOTX64.EFI
--------└─ LoaderDevicePartUUID = 01b85e5d-b970-400d-a409-08e6ae029415
------------└─ BLS entry
-----------------└─ kernel + initrd

There is " -----------------" insteed spaces because formatting problem.

The old problematic path:

Boot0001
└─ EFI\SYSTEMD\SHIM.EFI

is now only used as a backup.
