I've just seen this on a newish system with AMD 5700X CPU. "No action required", but does anybody know what it pertains to in case it's a harbinger of future trouble?
Am I right in assuming that this is not a memory ECC corrected error? (The system has ECC RAM. I would have expected to see "EDAC" in an ECC report)
kernel: [Hardware Error]: Corrected error, no action required.
kernel: [Hardware Error]: CPU:1 (19:21:2) MC11_STATUS[-|CE|-|-|-|-|-|-|-]: 0x80000000c8e1b163
kernel: [Hardware Error]: IPID: 0x0000000000000000
kernel: [Hardware Error]: Bank 11 is reserved.
kernel: [Hardware Error]: cache level: L3/GEN, tx: INSN
The system is running Rocky Linux 9.5 kernel 5.14.0-503.21.1.el9_5.x86_64
