Commen= t # 2 on bug 10165= 3 from Alexander Tsoy 
smu7_get_xclk() returns some crazy values when display is off.=
 And this value
depends on some state that changes every boot.

$ sudo journalctl -b -1 -o cat | grep reference_clock | sort | uniq -c
      4 amdgpu: reference_clock =3D 232169472, tmp =3D 0
      5 amdgpu: reference_clock =3D 2700, tmp =3D 0
$ sudo journalctl -b -o cat | grep reference_clock | sort | uniq -c
     16 amdgpu: reference_clock =3D 1305214976, tmp =3D 0
     12 amdgpu: reference_clock =3D 2700, tmp =3D 0


So now after reboot I get a different FAN speed when display is off:
$ cat /sys/class/hwmon/hwmon6/fan1_input
1057

When display is on, FAN speed is always consistent.
$ cat /sys/class/hwmon/hwmon6/fan1_input
937
