            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 at kernel-bugs.osdl.org
          Reporter: martin.tk at 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:

>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.
