Public bug reported:
I'm seeing an issue on an isolated host, howzit, in which it fails to
remove boot entries. In my limited testing this worked with the
6.2.0-20.20 kernel, but not the 21.21 or 23.23 kernel. I have not yet
tried any of the 6.3 kernels.
I've only seen this on one host so far, howzit, which is an arm64
server. I have tested on three other arm64 servers and they don't appear
to be impacted, so this could be some firmware issue. It adversely
impacts maas installs and will cause a mantic install (which is using
6.2.0-21.21) to fail because it can't modify the boot paths.
Here's what I see trying to remove a boot entry:
ubuntu@howzit-kernel:~$ efibootmgr -v
BootCurrent: 0005

BootOrder: 0005,0007,0004,0006

ubuntu@howzit-kernel:~$ sudo efibootmgr -B -b 0007
Could not delete variable: Invalid argument
The same command will work with the 6.2.0-20.20 kernel.
