You have passive trip point at 95C and critical at 120C. IIRC critical simply triggers system shutdown, and that can take time, so temperature may rise above 120C in this configuration. Is system tested for stable operation at 119C for extended periods? Because that's what this configuration means AFAICT. It seems little high to me. > + trips { > + target: trip-point { > + temperature = <95000>; > + hysteresis = <1000>; > + type = "passive"; > + }; > + > + sensor_crit: sensor-crit { > + temperature = <120000>; > + hysteresis = <1000>; > + type = "critical"; > + }; > + }; > + }; > + }; > + > timer { > compatible = "arm,armv8-timer"; > interrupts-extended = <&gic GIC_PPI 13 IRQ_TYPE_LEVEL_LOW>, Best regards, Pavel --FUw2zTv/EhYzo2Dc Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABECAB0WIQRPfPO7r0eAhk010v0w5/Bqldv68gUCad/+2wAKCRAw5/Bqldv6 8pZ6AJ4/1rQQAPa+nVQynsFxvpXxB5FXpgCeLdMTMI5o98F/dWqOeQEbSHLDge8= =jUiL -----END PGP SIGNATURE----- --FUw2zTv/EhYzo2Dc--
