After latest kernel upgrade my laptop (HP Elitebook 8440p) go to infinite loop
of boot with default (newer) kernel. While I select the previous kernel system
boot successfully. I did some investigation and found out that shim-install
script failing while trying to run efibootmgr command. I came into issue while
I decided to update boot loader settings from yast. I just increased timeout
and click save. After short while yast provide me with the message that
installation of the x86_64-efi platform was successful, but next there was a
statement:
requested operation failed: status=8000000000000002.
After that I have try to execute this script manually in console with debug
enabled. Result was quite strange, because the error status was returned from
all commands related to efibootmgr. All removing entries related commands
returned this status and finally the add new entry command return the same
status. Unfortunately after all this investigation I end up with the broken
boot loader. After reboot grub command prompt starts up and I had to enter
manually entries to boot successfully to the system. After uninstalling the
newest kernel and reapplying boot loader settings by yast boot loader is
working fine and grub is working correctly.

Right now I have not installed latest kernel, however due to latest fixes to
the kernel I'm eager to get it as fast as possible, so may I ask you for any
assistance with this issue.

Please let me know if you need any further information/log/experiments to drill
down into the route cause of the issue.
