nvidia-bug-report.sh appends .gz to --output-file when gzip is available, which silently produced empty nvidia-bug-report.txt in support bundles (cat looked for the uncompressed name that never existed). Also: a GPU that falls off the PCIe/NVLink bus (Xid 79) or gets flagged for Node Reboot Required (Xid 154) mid-SAT-run left every downstream test failing with generic, unrelated-looking errors (CUDA "unknown error", "unable to determine device handle") with no indication the GPU needed a physical power-cycle to recover. Detect these codes from SAT run logs and surface a plain-English "physical reboot required" message in the task's failure detail, the persisted component-status DB, a dashboard banner on the Hardware Summary card, and topology diagram GPU-node severity.
