Всем привет!
В syslog увидел множество сообщений об ошибках памяти вот такоего вида:

Соответственно, проблема с модулями CPU0 channel:0 slot:0 и CPU0 channel:2 slot:0
Всего в системе установлено 6*8Gb модулей. На плате маркировки типа A1, А2 и т.д.
Как понять, какие именно модули нездоровы (т.е. в какие слоты платы они установлены)?
UPD: попробовал смотреть через dmidecode:
# dmidecode -t memory | grep 'Locator: P'

Верно ли я думаю, что P0_Node0_Channel0_Dimm0 соответствует CPU_SrcID#0_Ha#0_Chan#0_DIMM#0 channel:0 slot:0, а P0_Node0_Channel2_Dimm0 - CPU_SrcID#0_Ha#0_Chan#2_DIMM#0 (channel:2 slot:0? Тогда получается, что мне нужны DIMMA1 и DIMMC1.
