Blender crashes with cycles and GPU rendering with AMD cards #86182

System Information
Operating system: Debian 10
Graphics card: AMD Radeon RX590 8Gb.

Blender Version
Broken: 2.92
Worked: 2.91

Blender will crash every time that cycles is used to render and blender will close.

Exact steps for others to reproduce the error
Open blender on Debian, Ubuntu or any distro either with a complete driver install or just the openCL portion using the latest Linux drivers (20.45 at the moment) go to settings, select GPU as rendering device (it will also happen choosing both CPU and GPU) chose cycles as render engine and GPU hit render/F12.

I've seen this marked as solved, but it fails on several distros with more than one model of AMD card therefore, is a mistake to state that this is solved with the 20.45 driver version or to fallback to 20.10

This is still an active bug.

I strongly recommend to avoid following misleading advice and downgrade your openCL driver. I downgraded to 20.10 for testing purposes with no avail blender will close anyway.

Needs to be reproduced. The last version working properly is 2.91.2
I've been following others reporting the same and pointing to mesa. I don't believe that this is the case LLVM doesn't haves much to do with it and also several driver versions won't do much.
I also tested it on EL8 and Fedora with the same results.

This is affecting 2.92 only. From the 2.83 to the above mentioned 2.91.2 everything works fine.

adding more info.

91c44fe885 may have solved the problem, you can try the latest daily build .
(If you can't, no problem, we can take it as resolved)

@mano-wii I'm downloading it now. I will posts the results as well as the driver version used. If everything goes well, I'll be more than happy! I'll be posting the results in a few moments.

Seems to work fine. :) I see a split kernel error (lamp related) but it stills renders both viewport and the scene with F12. I'm using the 20.50 amdgpu pro (only the openCL portion) I can confirm that this fixes the crash and viewport issues with a rx590 and rx580 8GB (and I guess that also with some navy cards with open bugs reports)
I also tested this on Fedora using the same method and works so Ubuntu users should be fine too.

Awesome news! Thanks!

It still freezes with volumes at the first sample on the viewport (Badly. the PC needs a hard reset) but is able to render the image using (for instance, volume scatter) hitting F12.
but is not being discussed here so you can consider this one solved and close it. Thanks for the help!

Good to know :)
Volume freezing may be related to the problem described in #84461 (Cycles: Split kernel error with OpenCL)
