            Bug ID: 213569
           Summary: Amdgpu temperature reaching dangerous levels
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.12, 5.11
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: martin.tk@gmx.com
        Regression: No

Ever since going to 5.11 version and later 5.12 the fan speed on my Radeon
RX550 is erratic causing the temperature to reach dangerous level.

sensors output:

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx:      825.00 mV 
fan1:         200 RPM  (min =    0 RPM, max = 3500 RPM)
edge:         +69.0°C  (crit = +97.0°C, hyst = -273.1°C)
power1:        7.03 W  (cap =  36.00 W)


I'm afraid it'll eventually kill my gpu.

I've already reported another bug for 5.11: 
https://bugzilla.kernel.org/show_bug.cgi?id=212107

From what I gather there were changes in fan control in 5.11. Is it possible to
disable those changes?
There were no issues on 5.10. Fan went to roughly 1000rpm, it was cool and
quiet.

The behaviour from 5.11 onward is dangerous, can cause hardware destruction.

I can confirm.

But in a different scenario. I'm using debian bullseye with lts kernel and
latest amdgpu firmware. I don't change any fan control mechanism.

5.10.44 and 5.10.45 works fine but 5.10.46 if i'm only start sway (wayland
window manager) my gpu usage is at 100% without doing anything.

It's a vega 56.

In my case it was watching a video that made the gpu reach 70°C

This is a legitimate bug which is present starting 5.12.13 and the issue was
said to have been fixed starting 5.13-rc8. I wanted to comment out of
reassurance that 70°C edge temperature for that GPU cannot damage it. Notice
"crit = +97.0°C" which is the throttle temperature.

The computer should shut down at the "emerg" temperature which is not present
in your sensors output, but should be +5.0°C over "crit" for your GPU.

You are probably hit by a recent regression introduced with kernel 5.10.46 and
5.12.13 (cf. https://bugzilla.kernel.org/show_bug.cgi?id=213561), where patches
are on its way
(https://lists.freedesktop.org/archives/amd-gfx/2021-June/065612.html). This is
not related to the original bug report here, I presume.

Thank you for explanation. I've never seen 70°C on my gpu before so to me it
looked scary.

Before those changes landed in 5.11 the usual temperature on my gpu would be
around 40°C. The fan would be around 1000rpm which on my gpu doesn't produce
any  perceivable sound.
