on two servers errors on different banks but with same "CPU_SrcID#0_Ha#0_Chan#2_DIMM#0"
I have problems identifying what memory module is generating the errors. Afaik this is the best indicator "EDAC sbridge MC0: CPU 0: Machine Check Event: 0 Bank 5:" I do not know why different banks generate the same "CPU_SrcID#0_Ha#0_Chan#2_DIMM#0" statement.
Currently the memory is allocated, so I cannot test it on a live system. If I would like to test this memory area after a reboot with memtester eg. would this be the correct way to do it?
memtester -p 0x00800000000 1G 1
