The reason is that acpi_early_init() enables the SCI and that interferes with the fast TSC calibration mechanism. Thus follow the original idea to execute acpi_early_init() before efi_enter_virtual_mode() to help the EFI people for now and we can revisit the other problem that commit 73f7d1ca3263 attempted to address in the future (if really necessary).
