4418核心板出现网络初始化失败
你好，我这边遇到通过reboot重启，无法加载网卡的现象。出现这种问题通常都是telnet后台之后，通过reboot重启会出现，断电重启目前没发现这种现象，而且这种现象一般是连续多次reboot才会出现。
请问这是什么问题，或者导致这种现象的原因有哪些？
启动过程打印信息：
No display device
Net: Board Net Initialization Failed
No ethernet found.
Hit any key to stop autoboot:0

Initializing random number generator... done.
Starting system message bus: done
Starting network: Cannot find device "eth0"

进后台ifconfig打印：
