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

--- Comment #5 from kernel@890.at --- Hi,
I have justed tested today the rotation on the HDMI output with one external monitor only, the same result, it seems that there is a rotation problem in general.
If you need any further information or testing, do not hesitate to ask ;)
cheers

--- Comment #10 from kernel@890.at --- just tried the 5.8.3 kernel with the same result, backtrace is attached.
This time I tried to rotate the display on the DisplayPort/USB-C, it does not seem to be related to the port.
