根据发来的错误提示分析：。
1，错误是由内核中的edac模块发出来的(具体的源码可参看)
2，而该模块的作用是检查ECC内存的错误处理，并报告错误，具体的edac说明如下：
EDAC Stands for "Error Detection and Correction". The Linux EDAC project comprises a series of Linux kernel modules, which make use of error detection facilities of computer hardware
来源:
解决方式：比较简单，根据出错分析的两点表明edac模块是检查到北桥的ECC校验控制单元产生错误而提示的，证明内存已出现的问题
需要更换内存。
