Where would kernel-level ECC corrections or uncorrectable memory errors be reported?

• A. Kernel logs
• B. User-space logs
• C. BIOS logs
• D. Firmware update logs

Answer: (A)

Hardware-level memory errors are reported to the operating system so it can manage reliability, and the kernel is the responsible layer for capturing and recording those events. When ECC corrections or uncorrectable memory errors occur, the kernel’s EDAC/memory subsystem logs them into the kernel log, which you can observe with tools like dmesg or journalctl -k. This is the place that records low-level hardware events; user-space application logs won’t capture these hardware fault details, BIOS logs pertain to the boot firmware, and firmware update logs relate to the update process rather than runtime memory faults.
