PCI ROOT HID fail=0x5 ACPI Linux错误一般解决之道

我的两台服务器里dmesg里有以下错误,请教是什么原因?

os :rhel4.4

解决方式:

启动选项中增加参数:
修改/boot/grub/menu.lst文件,在启动的核心kernel那行最后加上
acpi=off noapic 或者acpi=noapic或者acpi=off
1)acpi=off禁止了一些电源高级管理功能,对应用程序没有影响。
2)noapic改变了中断方式,对应用也没有影响。
如果你的linux系统网卡无法收发数据,磁盘阵列光纤卡无法访问磁盘、系统启动时报ACPI然后停止等错误时,可以尝试上面的方法,会有意想不到效果哦!
