Como remover avisos de acpi [duplicados]

Question

Estes são os avisos quando eu corro dmesg .

ACPI: Deleted _OSI(Windows 2012)
ACPI: Deleted _OSI(Windows 2013)
ACPI: RSDP 00000000000f0410 00024 (v02 INTEL )
ACPI: XSDT 00000000bdfaad98 000B4 (v01 INTEL    ROMLEY 06222004 INTL 20090903)
ACPI: FACP 00000000bdfaa918 000F4 (v04 INTEL    ROMLEY 06222004 INTL 20090903)
**ACPI Warning: Invalid length for Pm1aControlBlock: 32,** using default 16 (20090903/tbfadt-615)
ACPI: DSDT 00000000bdf8f018 19656 (v02 INTEL    ROMLEY 00000002 INTL 20100331)

E no BIOS não há configuração de ACPI para desativar, então eu tento o acpi=off no arquivo grub.conf , mas depois disso, nenhum registro de ACPI está chegando. O que devo fazer para remover o aviso de acpi?

    

Answer 1

De acordo com a documentação do RHEL :

This message is informational only. It does not indicate anything is wrong and can be safely ignored.

Root Cause

The system hardware defines a 32-bit register size for its ACPI Pm1aControlBlock and Pm2ControlBlock, however the ACPI specification defines a 16-bit register size for the Pm1aControlBlock and 8-bit register size for Pm2ControlBlock.

This message is telling you that the kernel's ACPI code is ignoring the hardware register size, and using the ACPI specification size.
