[Bug 108098] Ryzen 7 2700U, amdgpu, graphics freezes on 4.19.0-041900-generic

--- Comment #8 from Antonio Chirizzi antonio.chirizzi@gmail.com --- 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
