1、錯誤信息記錄位置查看find /var/log -type f|xargs grep "00:0b"
關鍵字也可以選擇CRS
[root@door toor]# find /var/log -type f|xargs grep "00:0b" (使用最高權限查看,權限低 會拒絕find指令的查看)
/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、查看錯誤詳細信息:sudo gedit /var/log/messages (編輯器隨便吧)
Ctrl+F 定位到“CRS“
這段信息是有用的:

開始使用acpi=off 加到內核參數上,開機錯誤任在,鼠標移動不流暢了!!這裏應該是還註冊了其他設備的原因。
參考內核參數這:http://www.jinbuguo.com/kernel/boot_parameters.html
發現這個地方找到這個參數:
- pnpacpi=off
- 禁用ACPI的即插即用功能,轉而使用古董的PNPBIOS來代替。
3、 sudo gedit /boot/grub/grub.conf

把日誌 都刪除root shell: find /var/log -type f -exec rm -v {} \; (分號要有的)
保存,重啓, 再試一次 find /var/log -type f|xargs grep "00:0b" 這時候啥也沒了!!!到此錯誤解決。
