System Information

Operating system:	Debian (Linux)
Graphics card:	Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7)

Blender Version
Broken: 3.1.2 Linux 64
(example: 2.79b release)
(example: 2.80, edbf15d3c0, blender2.8, 2018-11-28, as found on the splash screen)
Worked: 2.93.5

Blender closes abruptly when I add a subdivision surface modifier to the default cube.

Exact steps for others to reproduce the error
Download and unpack blender 3.1.2.
Launch blender.
Under "New File" on the splash screen, choose "General."
The default cube is already selected.
Using the interface on the right, choose the wrench-labeled "Modifier Properties" tab, select "Subdivision Surface" from the "Generate" column in the "Add Modifier" dropdown.
Blender crashes.

I launched blender from a command line to capture this output:

# Python backtrace

I saw, in an issue reported by a windows user, a suggestion to turn off GPU Subdivision under preferences. I have done this and it seems to be a successful work-around.

I just downloaded this version of blender and immediately had this problem after unpacking and launching. I had not turned on the GPU Subdivision preference or made any other preference changes before encountering the problem.

I reasoned this is not a duplicate issue of the one I saw from the windows user because the behaviour they saw was different (not a silent crash).

Thanks for update.

@kevindietrich Can you tell if this is issue with GPU driver or could be bug in our code?

This error Error: Too many compute shader storage blocks (9/8) should have been fixed already, so there might a bug in the code. I would need to plug my AMD GPU to investigate further. However, updating driver should fix it.

So libgl1-mesa-dri:amd64 might be the one supporting 8 SSBOs only in my current configuration. The system is a new one, it is possible that the wrong libraries are chosen (e.g. old software mesa in debian bullseye).

I created a small "explanation patch" to do some exception-handling and display a hint in case of a missing shader.

It would be nice if a driver which supports 8 storage blocks only (like libgl1-mesa-dri [20.3.5-1]) would be detected earlier. I will have a look at my system to determine why mesa instead of the nvidia-driver was choosen in this case.
