There has been a lot of discussion over the years about Ryzen ECC support, function and reporting. I managed to see an ECC corrected error reported in the wild.

Code:
[Hardware Error]: Corrected error, no action required.
[Hardware Error]: CPU:0 (19:21:0) MC18_STATUS[Over|CE|MiscV|-|AddrV|-|-|SyndV|-|CECC]: 0xdc2041000000011b
[Hardware Error]: Error Addr: 0x00000002958be000
[Hardware Error]: IPID: 0x0000009600150f00, Syndrome: 0xe93e20000a800602
[Hardware Error]: Unified Memory Controller Extended Error Code: 0
[Hardware Error]: Unified Memory Controller Error: DRAM ECC error.
[Hardware Error]: cache level: L3/GEN, tx: GEN, mem-tx: RD
CPU: Ryzen 5800x
RAM: 2x 16GB 3200 ECC DIMMs from NEMIX RAM
Motherboard: ASRock Rack X570D4U-2L2T
OS: RHEL 8.3

Unfortunately, the RHEL kernel edac driver does not recognize the MC of the zen3 part so I can't see if its stat counters recorded the event.

Not sure what to make of the error. This system has been rock solid so far. Anyway... posting here in case anyone finds this interesting.
