内核错误

kway

自己设计的底板，用的a40i_c的核心板，使用原始的镜像文件，启动后提示如下错误，请问是什么问题，该如何解决？

PS：在网上搜索过解决“NETDEV WATCHDOG: eth0: transmit timed out”的方法：
/boot/grub/menu.lst文件，在启动的核心kernel那行最后加上
acpi=off noapic

不知道是我编译的不对还是怎么，重新生成镜像后还是会出现一样的问题

您的核心板在我们的底板上用，使用同一版镜像，会存在这种问题吗？如果没有，说明核心板是好的，您需要看一下您硬件设计的和我们底板哪些地方不同。从打印信息看是网口报出来的信息，您烧写我们最新的用户资料2020.12.18的镜像试一下。

核心板是好的，的确是phy芯片与开发板有区别，我们底板用的是YT8521SH的rgmii，请问有关于修改内核驱动的相关教程吗？刚接触这方面，不太熟悉

您联系一下和您对接的销售，让她给您提供一下百兆千兆双网口扩展的方法，里边有关于这部分的描述。
