Comment 4 Matthias 2020-10-03 02:21:48 UTC 
I installed the latest update (https://bodhi.fedoraproject.org/updates/FEDORA-2020-46973824f1) and did a quick check. Blender still crashes when trying to apply a texture to the standard cube in the Shader Editor.

This is not a bug in Blender 2.90. I installed the version from Flathub (https://flathub.org/apps/details/org.blender.Blender). It works as expected. 

The issue is with the Fedora rpm.

Comment 6 Luya Tshimbalanga 2020-10-03 19:00:43 UTC 
I confirm the bug which is caused by eithr LLVM 11.0 or the driver in Fedora 33 when using either command from comment #0:

- LLVM triggered Diagnostic Handler: Illegal instruction detected: VOP* instruction violates constant bus restriction
renamable $vgpr4 = V_CNDMASK_B32_e32 32768, killed $vgpr5, implicit killed $vcc, implicit $exec
LLVM failed to compile shader
radeonsi: can't compile a main shader part
LLVM triggered Diagnostic Handler: Illegal instruction detected: VOP* instruction violates constant bus restriction
renamable $vgpr4 = V_CNDMASK_B32_e32 32768, killed $vgpr4, implicit killed $vcc, implicit $exec
LLVM failed to compile shader
radeonsi: can't compile a main shader part
Writing: /tmp/blender.crash.txt
Segmentation fault (core dumped)

It looks like radeonsi cannot compile the shader for some reasons with this highlight:
radeonsi: can't compile a main shader part

Could you run the current installed Blender via terminal and post the traceback here? Let know which GPU do you use.

Addiitonally, install this scratch build below from LLVM 9.0 and let know if the issue still occur.

Comment 7 Matthias 2020-10-04 10:53:29 UTC 
I guess with traceback you mean the blender.crash.txt that is linked in the terminal output? Other than that there is not much in the terminal. Do I need to run with some additional option?

I attached the crash text files for the latest version in updates-testing and the one that you asked me to test above.

Regarding the test version with LLVM 9.0, it also crashes. Same behaviour as the version in the repo.

As for my hardware:

Operating System: Fedora 33
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.73.0
Qt Version: 5.15.1
Kernel Version: 5.8.13-300.fc33.x86_64
OS Type: 64-bit
Processors: 8 × Intel® Xeon® CPU E3-1230 v5 @ 3.40GHz
Memory: 15.6 GiB of RAM
Graphics Processor: GeForce GTX 1060 6GB/PCIe/SSE2

I am using the rpmfusion nvidia drivers. Version is 450.66.

However, I also tried with a laptop. Same crash happens there as well. This other machine has the following config:

Operating System: Fedora 33
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.73.0
Qt Version: 5.15.1
Kernel Version: 5.8.13-300.fc33.x86_64
OS Type: 64-bit
Processors: 8 × Intel® Core™ i5-8365U CPU @ 1.60GHz
Memory: 7.6 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620

It crashes with both versions. blender-1:2.90.1-1.fc33.x86_64 and blender-1:2.90.1-1.llvm9.fc33.x86_64.
