使用centos引导内核错误:kernel: pnp 00:0b: can't evaluate _CRS: 8

环境:系统Centos6.6   硬件环境 SAMSUNG RV420

1、错误信息记录位置查看find /var/log -type f|xargs grep "00:0b"    

关键字也可以选择CRS

[root@door toor]# find /var/log -type f|xargs grep "00:0b"  (使用最高权限查看,权限低 会拒绝find指令的查看)

/var/log/messages:Jul 26 11:35:17 door kernel: pnp 00:0b: can't evaluate _CRS: 8
/var/log/dmesg:pnp 00:0b: can't evaluate _CRS: 8

/var/log/dmesg:pnp 00:0b: Plug and Play ACPI device, IDs PNP0c01 (active)


2、查看错误详细信息:sudo gedit /var/log/messages    (编辑器随便吧)


Ctrl+F 定位到“CRS“

这段信息是有用的:

Jul 26 11:35:17 door kernel: pnp: PnP ACPI init  (PnP:即插即用,ACPI:高级电源管理接口)  ---初始化
Jul 26 11:35:17 door kernel: ACPI: bus type pnp registered

Jul 26 11:35:17 door kernel: ACPI: ACPI bus type pnp unregistered  --注册失败了一个


开始使用acpi=off 加到内核参数上,开机错误任在,鼠标移动不流畅了!!这里应该是还注册了其他设备的原因。


参考内核参数这:http://www.jinbuguo.com/kernel/boot_parameters.html

发现这个地方找到这个参数:

pnpacpi=off
禁用ACPI的即插即用功能,转而使用古董的PNPBIOS来代替。
然后第三步

3、 sudo gedit  /boot/grub/grub.conf


title CentOS 6 (2.6.32-504.el6.i686)
    root (hd0,3)
    kernel /vmlinuz-2.6.32-504.el6.i686 ro root=UUID=33b23ad2-f922-4329-8f8f-f3a145147587 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM  pnpacpi=off

把日志 都删除root shell: find /var/log -type f -exec rm -v  {} \;            (分号要有的)

保存,重启, 再试一次   find /var/log -type f|xargs grep "00:0b"   这时候啥也没了!!!到此错误解决。
