This document provides a general troubleshooting procedure for the NVIDIA System Management (NVSM) alert NV-CPU-XX, which indicates that a CPU has reported an internal error. The article outlines how to verify whether the alert represents an active hardware issue or a historical/stale alert and describes the recommended remediation steps.
| Item | Description |
| Alert ID | NV-CPU-XX |
| Component | Processor (CPU) |
| Severity | Critical |
| Typical Message | System
entered degraded mode, CPU is reporting an error. |
The alert may be generated due to one or more of the following:
Run: sudo nvsm show health
Confirm whether the system reports any unhealthy components.
Collect diagnostic information:
The generated archive is typically located under:
/tmp/nvsm-health-<hostname>-<timestamp>.tar.xzThis bundle should be attached when opening a support case with NVIDIA.
Display active alerts
Verify whether the NV-CPU-XX alert is still active.
Check for hardware events recorded by the Baseboard Management Controller (BMC):
Look for entries related to:
The presence of CPU-related SEL entries may indicate an actual hardware issue.
Search for Machine Check Exceptions (MCE) and hardware errors:
Also review: dmesg | grep -Ei "mce|hardware|cpu|edac"
These logs help determine whether the operating system detected CPU hardware errors.
Compare the findings from the previous steps.

In this case:
Indicators include:
In this case, the alert may be historical and can typically be cleared after verifying that no active hardware fault exists.
If NVIDIA Support confirms that the alert is stale, clear the NVSM database and BMC SEL.
Stop NVSM: sudo systemctl stop nvsm
Remove the NVSM alert database: sudo rm /var/lib/nvsm/sqlite/nvsm.db
Clear the BMC SEL: sudo ipmitool sel clear
Remove archived SEL logs: sudo rm /var/log/bmc_sel_archive_for_BMC_*.log
Restart NVSM: sudo systemctl start nvsm
After cleanup, verify:
sudo nvsm show healthsudo nvsm show alertssudo ipmitool sel list
Expected results:
Contact NVIDIA Enterprise Support if:
When opening a case, include:
sudo nvsm dump health)ipmitool sel list)journalctl -k)
