GPU thermal critical
GPU die temperature at or above the HW slowdown threshold, or the kernel reports a hardware thermal slowdown. A software thermal slowdown at the card's thermal target (normal load behavior) does not fire. Sustained operation at thermal limits accelerates wear and reduces throughput. Boot grace 300s for post-boot sensor stabilisation.
