Everyone who is attempting to upgrade BIOS, beware that the Ubuntu EFI
boot option is erased during the upgrade process. The entry in the "Boot
Priority Order" is gone after the upgrade, and you will need to install
EFI grub to be able to continue using Ubuntu in the EFI mode. The
upgrade process also sets the boot mode to "Secure Boot". If you need to
continue booting into Ubuntu after the upgrade, make sure that you can
boot Ubuntu into the CSM mode, and use the CSM mode until you have time
to install EFI grub.

The BIOS upgrade comes without any changelog. Can anyone confirm that
this upgrade indeed fixes the bricking problem?
