Xid
A system of error codes written to the kernel log when the NVIDIA GPU driver detects hardware or firmware anomalies. Each number corresponds to a specific fault root cause (for example, Xid 79 indicates the GPU has fallen off the PCIe bus) and is used for operations triage.
Timeline (last 90 days)
NVIDIA's Xid numbering system covers GPU hardware and firmware errors, with each number corresponding to a specific class of failure root cause, for example Xid 79 indicates the GPU has fallen off the PCIe bus, Xid 48 corresponds to an uncorrectable double-bit ECC memory error, Xid 74 involves an NVLink link failure, and Xid 119/120 relate to GSP firmware timeouts.
AI-Node-Sentinel's Xid lookup table covers only seven codes (13, 31, 48, 74, 79, 119, 120), and all codes outside the table return None and are escalated to a human, with refusal to guess being the most important safety property of the pipeline.
