The kernel log shows many instances of the following EDAC error:
EDAC MC0: 1 CE ie31200 CE on unknown memory (csrow:3 channel:1 page:0x0 offset:0x0 grain:1 syndrome:0x1c)
The thing is... there is no csrow #3 on my system (output truncated for visibility):
$ 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
How can that be? Is there actually a faulty memory device? How can I identify which it is?
More information that may help:
$ cat /sys/devices/system/edac/mc/mc0/ce_count

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