linux – 内核：dmesg中的EDAC MC0垃圾邮件

我在dmesg中有垃圾邮件,其中包含：

kernel:EDAC MC0: UE page 0x0,offset 0x0,grain 1073741824,row 3,labels ":": i3200 UE

知道什么是假的吗？

这里是加载模块：

# lsmod | grep edac
i3200_edac              3330  0
edac_core              46581  2 i3200_edac

edac-util不显示任何错误

# edac-util -v

mc0: csrow7: ch1: 0 Corrected Errors

解决方法

echo 0 > /sys/module/edac_core/parameters/edac_mc_log_ce

将在下次重新启动之前阻止控制台上的垃圾邮件.

基本上ce_errors是可纠正错误的缩写(在ram之外也没有“缺陷”).

见kernel docu about edac
和edac wiki
更多细节.

虽然我可能完全错了,但我们有一台服务器(ECC RAM),因为没有无法纠正的错误,memdisk没有显示任何问题,我让它使用相同的ram运行,更改输出,开始监控无法纠正的错误和对我们来说没有进一步的问题.
