Comment # 8 on bug 108098 from Antonio Chirizzi

Hello again,

I have been testing my laptop with the AMD Ryzen 7 2700U with latest the Ubuntu
kernel 4.19.0-041900-generic for the last 2 weeks.

It does not freeze and everything works well if I use the WIFI at 2 GHz.

It DOES FREEZE if I use the WIFI at 5 GHz.

What I don't understand is that no amdgpu kernel fault lines appear in the
kern.log if I use the 2 GHz wifi.

How is that connected?

Thanks,

-Antonio
