What changed

Link width by release

LANES

v1.6v1.7v1.8v1.9

Four captured values, not continuous monitoring.

THE EVIDENCE

Captured link width changed

OBSERVED

BASELINE · v1.8LinkSta: Width x8

CURRENT · v1.9LinkSta: Width x1

A captured difference. It does not establish why the link negotiated fewer lanes.

YOUR NEXT CHECK

Recheck both ends of the link.

Capture the endpoint and upstream port after retraining. Compare their Link Status and the test conditions.

LESS GUESSWORK. A CLEARER NEXT STEP.

Keep the evidence.
Keep moving.
