Some errors have multiple sub sections like below:
[ 1442.070522] {2}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 0
[ 1442.070528] {2}[Hardware Error]: event severity: corrected
[ 1442.070531] {2}[Hardware Error]: sub_event[0], severity: corrected
[ 1442.070534] {2}[Hardware Error]: section_type: memory error
[ 1442.070537] {2}[Hardware Error]: error_status: 0x0000000000000000
[ 1442.070539] {2}[Hardware Error]: sub_event[1], severity: corrected
[ 1442.070541] {2}[Hardware Error]: section_type: memory error
[ 1442.070543] {2}[Hardware Error]: error_status: 0x0000000000000000
