Ubuntu 14.04是否可以使用4.7内核（或更高版本）？

我们尝试过，但是无法成功启动。安装4.7内核后重新启动，它显示以下消息并粘贴在此处：

/scripts/init-top/udev: line 14: can't create /sys/kernel/uevent-helper:
Permission denied.
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check root delay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules, ls /dev) ALERT!
/dev/disk/by-uuid/6f... does not exist. Dropping to a shell.
