标题: 关于内核崩溃的问题
A9核心板信息如下：

processor    : 2
BogoMIPS       : 790.52
processor    : 3
BogoMIPS       : 790.52
Features       : swp half thumb fastmult vfp edsp neon vfpv3
CPU implementer : 0x41
CPU architecture: 7
CPU variant    : 0x2
CPU part       : 0xc09
CPU revision : 10

在TCP通信时，内核有时（概率比较高）会出现发下错误消息：
[sdhci_pre_dma_transfer] invalid cookie: data->host_cookie 45408 host->next_data.cookie 45409

CPU挂了，内核出问题了，各种命令都不生效了，只能掉电关机~
怎么破？？？？？？？？？？？？？？？
