安装内核时dkms挂起

我正在使用Ubuntu GNOME 15.04。我想使用MPTCP，为此我已经下载并编译了修改后的内核（https://github.com/multipath-tcp/mptcp，分支mptcp_v0.90）。我至少需要3.18内核才能进行Displayport传递。安装模块和头文件后，在安装内核时进入以下行

run-parts: executing /etc/kernel/postinst.d/dkms 3.18.19+ /boot/vmlinuz-3.18.19+

然后停止。从dkms脚本中删除“> &&”之后，我得到以下输出：

hp@hp-desktop:~/git/mptcp$ sudo make install
sh ./arch/x86/boot/install.sh 3.18.19+ arch/x86/boot/bzImage \
  System.map "/boot"

点不断增加，但是即使经过几个小时，该过程仍未完成。

编辑：让它坐了几个小时后，它确实停了下来，并给了我这个错误：
