From e4cc4733ebd4c6fc77de5f0a9963e9a938e57e5d Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Thu, 11 Aug 2016 12:39:54 -0700 Subject: reef: Increase TSR2 threshold to 100 This is a temporary work-around since the current threshold of 70 on TSR2 results in thermal trip and shutdown while the kernel is booting. Changing this threshold to 100 allows kernel to boot up to userspace. Following values were read: $ cat /sys/class/thermal/thermal_zone4/temp 81800 $ cat /sys/class/thermal/thermal_zone4/type TSR2 BUG=chrome-os-partner:56155 BRANCH=None TEST=Boots to OS.
