Tested with a processor from 10h family on a system where correctable
ECC errors occur semi-regularly, sometimes in bursts.
Here is an example of three consecutive MCE reports:
MCA: Bank 4, Status 0xdc544100e0080a13
MCA: Global Cap 0x0000000000000106, Status 0x0000000000000000
MCA: Vendor "AuthenticAMD", ID 0x100f43, APIC ID 0
MCA: CPU 0 COR OVER BUSLG Responder RD Memory
MCA: Address 0x216a6f1d0
MCA: Misc 0xc01b0fff01000000
MCA: Bank 4, Status 0xdc544100e0080a13
MCA: Global Cap 0x0000000000000106, Status 0x0000000000000000
MCA: Vendor "AuthenticAMD", ID 0x100f43, APIC ID 0
MCA: CPU 0 COR OVER BUSLG Responder RD Memory
MCA: Address 0x216be3040
MCA: Misc 0xc01b0fff01000000
MCA: Bank 4, Status 0xdc544100e0080a13
MCA: Global Cap 0x0000000000000106, Status 0x0000000000000000
MCA: Vendor "AuthenticAMD", ID 0x100f43, APIC ID 0
MCA: CPU 0 COR OVER BUSLG Responder RD Memory
MCA: Address 0x217b3c720
MCA: Misc 0xc01a0ffb01000000
The first two were triggered by the interrupt, the last one is
from the periodic polling. Note the values in Misc.
