Description Rodrigo Luglio 2021-04-28 12:48:43 UTC

I have a macbook pro with vega 20 which uses the amdgpu firmware vega12 and when i boot any distro the graphics glitch and the computer freezes.
 If i install amdgpu pro on ubuntu it works flawlessly. Would you guys help me debug this and fix for upstream? 

Let me know what can I send to complement the information required for analysis, like logs or dmesg. I would be very happy to help and participate on this.

Please, excuse me if this is not the right place for me to ask this kind of thing, and please if you can, kindly redirect me to the right place.

amdgpu pro uses the same driver as upstream, just packaged so that you can install it on enterprise distros, so the code is the same.  What driver package version did you use?  What upstream kernels have you tried?  Please include the dmesg output from the working and non-working cases.

Note that you don't need to file two bugs.
