linux关闭ACPI电源管理模块

一、运行环境

# cat /etc/redhat-release
CentOS release 6.2 (Final)
# uname -a
Linux web-server- 2.6.-.el6.x86_64 # SMP Tue Dec  :: GMT  x86_64 x86_64 x86_64 GNU/Linux

# 硬件
DELL R420 SATA .2K 500G *
# CPU
Intel(R) Xeon(R) CPU E5-  @ .90GHz

二、服务器异常重启日志

# grep Error /var/log/messages
Dec   :: web-server- kernel: ERST: Error Record Serialization Table (ERST) support is initialized.
Dec   :: web-server- kernel: ACPI Error: No handler for Region [SYSI] (ffff88022accf420) [IPMI] (/evregion-)
Dec   :: web-server- kernel: ACPI Error: Region IPMI() has no handler (/exfldio-)
Dec   :: web-server- kernel: ACPI Error (psparse-): Method parse/execution failed [\_SB_.PMI0._GHL] (Node ffff88022acd38f8), AE_NOT_EXIST
Dec   :: web-server- kernel: ACPI Error (psparse-): Method parse/execution failed [\_SB_.PMI0._PMC] (Node ffff88022acd3998), AE_NOT_EXIST

# grep Error /var/log/dmesg
ERST: Error Record Serialization Table (ERST) support is initialized.
ACPI Error: No handler for Region [SYSI] (ffff88022accf420) [IPMI] (/evregion-)
ACPI Error: Region IPMI() has no handler (/exfldio-)

三、关闭acpi服务

/etc/init.d/acpid stop
chkconfig acpid off

# vim /boot/grub/grub.conf
在kernel行最后加上 acpi=off noacip
