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-40 2.6.32-220.el6.x86_64 #1 SMP Tue Dec 6 19:48:22 GMT 2011 x86_64 x86_64 x86_64 GNU/Linux

# 硬件
DELL R420 SATA 7.2K 500G *2
# CPU
Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz

二、服务器异常重启日志

# grep Error /var/log/messages

Dec  6 05:15:24 web-server-40 kernel: ACPI Error: No handler for Region [SYSI] (ffff88022accf420) [IPMI] (20090903/evregion-319)

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
