请教一下6UL-C2以太网报错问题

核心板和底板一开始用你们的时候  还好，很正常，



然后使用了一段时间之后，期间没有烧过系统，突然出现了

Reconfiguring network inte**ces... [    8.755725] fec 2188000.ethernet eth0: Freescale FEC PHY driver [Micrel KSZ8081 or KSZ8091] (mii_bus:phy_addr=2188000.ethernet:00, irq=-1)

done.

然后不动的话 还会出现

freescale login: [   33.822151] nf_conntrack: automatic helper assignment is deprecated and it will be removed soon. Use the iptables CT target to attach helpers instead.

正常PING的时候还是能 ping的  通，  reboot 也正常。

后来我自己也做了个工程相关的底板，按照你们的C2底板原理图照抄的。

也出现

然后不动它 果断时间  出现

freescale login: [   33.822151] nf_conntrack: automatic helper assignment is deprecated and it will be removed soon. Use the iptables CT target to attach helpers instead.

然后 登陆的话正常，

再reboot  就挂了

启动不了 报错下图
