This is a newer warning due to a kernel upgrade.

It allows the linux kernel to interact with CPU security features developed by intel.

The message does not harm anything

You can either:

ignore it
make a change in the bios to enable the feature.
1. the cpu may be capable and the bios not.
2. If you can't find the "switch" in the bios then:
  1. Your motherboard cannot use sgx
  2. Your BIOS is too old.
3. If after all you determine your hardware cannot use sgx then you can hide it
add nosgx as a boot parameter.
1. In the file /etc/default/grub you add nosgx in the follwoing section
  1. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nosgx"
2. sudo update-grub
3. reboot and you will no longer see the error message.

Since upgradeing to 22.04 there are lots of acpi errors that appear during boot and once in a while prevent a clean boot.

Open the files /etc/default/grub

add loglevel=3 to ignore those errors.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3"
