Its kernel version is 2.6.18-274. el5 kernel compilation 3. download kernel source code 2.6.32.60 to centos and decompress it. 4. create a simple config: make localmodconfig for the local Machine (Press enter if prompted) (local config is supported in Versions later than 2.6.32) 5. in. add CONFIG_SYSFS_DEPRECATED_V2 = y to the config file. Otherwise, the/dev/root cannot be found during the startup of the new kernel.
