用的make oldconfig命令配置的内核，需要选择的我都选的是n或者m，需要键入其他内容的我选的都是默认内容，开机之后出现
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for right device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/1d82191f-51f8-4b55-8af7-4024eb04cb39 does not exist. Dropping to shell!
并且在输入exit之后不能正常启动系统，估计是内核编译时的配置问题，求解，4.2.1稳定内核按上述步骤编译后无问题
