内核日志显示许多以下 EDAC 错误实例：
EDAC MC0: 1 CE ie31200 CE on unknown memory (csrow:3 channel:1 page:0x0 offset:0x0 grain:1 syndrome:0x1c)
问题是......我的系统上没有csrow #3（为方便查看，输出被截断）：
$ ls -l /sys/devices/system/edac/mc/mc0
drwxr-xr-x 3 root root 0 May 19 10:53 csrow0
drwxr-xr-x 3 root root 0 May 19 10:53 csrow1
怎么会这样？实际上内存设备故障？如何识别是哪个设备？
更多可能有帮助的信息：
$ cat /sys/devices/system/edac/mc/mc0/ce_count

$ cat /sys/devices/system/edac/mc/mc0/csrow?/ce_count
