No fscking way is ASUS going to fix their BIOS for Linux users.
I understand he said that Windows had the same problem.
That's why I think it unlikely treating it as a software bug will help.
Even if it is.
There's no way to test fixes, because supposedly working kernels (windows) still exhibit the issue.
But sure, testing a live media can't hurt. Just an update on the tests you asked me to run: until now I could not get the live USB to boot (it hangs at some point), and I can't let it heat idle to see what happens, because it reboots after a while. The fan does sound a bit louder, but this is only my inaccurate ear measuring. I had to go to work, I will try troubleshooting why the boot fails this evening, and if I still cannot boot, I'll try to start

: the live USB with a hot CPU, to see if the fan goes berserk as it should. Good news, I think! The live USB did not seem to work: it still could not get it to boot, and even if I start it with a hot (>80°C) CPU, the fan doesn't seem to step up.
But. I landed on a list of kernel flags, and I tried a couple of them out... just to see? Anyway, it turns out that if I boot my tumbleweed system with "thermal.off=1", I lose the main temperature sensor, and I *can* force the fan to full speed with pwm1_enable=1. The fan speed reading is not any useful, but I can hear that the fan is notably faster. And the remaining temperature readings are stabilized.
So, the fan is working at least.
After seeing all that, I rebooted (with the default boot flags this time), pwm1_enable was still set to 1 (before that, it was always 2 after a reboot). Again, I could control the fan (stop it or set it to full speed), and this time the fan speed readings seem to be accurate (at least for high speeds). I have now set pwm1_enable to 2 (automatic), I will see how the temperature is in 30-60 minutes.
Well, you've proven it's a kernel thing. Or a kernel-BIOS interaction. So I'd suggest trying to get help from the kernel ML mentioned upthread, where the wise guys are. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
