检查一下，这里是the link，这是不同的内核编译日志，所以你可以安装成功的版本内核，然后清理编译字典，重新编译它。

我认为它可以解决您的问题。

在我的Ubuntu 14.04.3 x86_64情况下，我安装了内核3.18.7，这里是解决方案

 $ cd /tmp

 $ wget \
 kernel.ubuntu.com/~kernel-ppa/mainline/v3.18.7-vivid/linux-headers-3.18.7-031807_3.18.7-031807.201502110759_all.deb \
 kernel.ubuntu.com/~kernel-ppa/mainline/v3.18.7-vivid/linux-headers-3.18.7-031807-generic_3.18.7-031807.201502110759_amd64.deb \
 kernel.ubuntu.com/~kernel-ppa/mainline/v3.18.7-vivid/linux-image-3.18.7- 031807-generic_3.18.7-031807.201502110759_amd64.deb

 $ sudo dpkg -i linux-headers-3.18*.deb linux-image-3.18*.deb

 $ sudo reboot

Answer 2

我遇到了同样的问题，我的解决方法是在 v4l / .config 文件中设置 CONFIG_VIDEO_SAA7164 = n 。在此之后，编译正确执行。

Answer 3

运行make menuconfig并导航菜单以从构建中禁用saa7164驱动程序。层次结构应该类似于DEVICE DRIVERS - ＆gt;多媒体驱动程序 - ＆gt; VIDEO4LINUX / DVB驱动器 - ＆gt; PCI板（我不认为它是PCIe的单独子菜单）然后禁用saa7164的驱动程序。
