dmesg output

Hi,

I have a lenovo E15 gen2 laptop running, with a Ryzen 7 4700U renoir Vega 7, on
a 5.8 ubuntu mainline kernel including the latest firmware files (git).

System seems stable so far when running 2 monitors (internal display, and
external display on DP).

When adding a third monitor on the HDMI output and rotating this monitor, the
system crashes with a null pointer dereference.


any help would be appreciated

cheers
