System Information
Operating system: macOS-13.0.1-x86_64-i386-64bit 64 Bits
Graphics card: Intel(R) Iris(TM) Plus Graphics OpenGL Engine Intel Inc. 4.1 INTEL-20.2.44
MacBookPro16,2
32GB RAM

Blender Version
Broken: version: 3.4.0 Beta, branch: blender-v3.4-release, commit date: 2022-11-24 16:55, hash: 959f3cd645
Worked: unknown, I tried several builds after Intel GPU metal is enabled in daily builds.

Short description of error
Blender crash once starts rendering. It can also trigger to system hang (not responsive GUI) and the after while system trigger reset.
Last traces when launching Blender from shell:

CommandBuffer Failed: cycles_metal_integrator_intersect_shadow

Refer to the Cycles GPU rendering documentation for possible solutions:
https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html

-[_MTLCommandEncoder dealloc]:131: failed assertion `Command encoder released without endEncoding'
zsh: illegal hardware instruction ./Blender

From Xcode debugger:

2022-11-29 20:37:18.198099+0100 Blender[22800:105451] Execution of the command buffer was aborted due to an error during execution. Caused GPU Timeout Error (00000002:kIOAccelCommandBufferCallbackErrorTimeout)

Exact steps for others to reproduce the error

Load scene from https://download.blender.org/demo/test/classroom.zip
Enable only 'Intel Iris Plus Graphics' in Metal preferences
Select GPU Compute
Render Image

I tried few other Cycles demos: barbershop, car demo, Italian flat, lone monk, monster under bed. All same ends with Blender crash.
For car demo for a second I saw first sample result and then crash.

Default cube works however.

Hi, thanks for the report. Crash could be related to #101787 (GPU Metal Render fails with error "CommandBuffer Failed: cycles metal integrator_ reset" on M2 MacBook Air)
As far as I understand, crash is due to out of memory in #101787, which is probably not the reason here for crash
@brecht can you check?

@mmostajab @Michael-Jones, can you check? Not sure if there is an issue with Intel in general or perhaps this particular GPU.

Hi @brecht
I managed to reproduce the issue on Intel Iris GPU on a machine with 8GB ram. We think it is probably running out of memory. We will investigate it more.

Unfortunately fix doesn't catch memory issues and Blender crashes. Interesting that Blender from master branch works better. Sometimes works few times in row without issue, and another time keeps crashing and leads to hang system. I presume this one has lower memory footprint.

I can not reproduce issue with Blender from master branch now, same build as before.
Still, the 3.4 release keeps crashing with fix manually applied.

So backporting the same fix to 3.4 would not work.
@Michael-Jones , can you also verify whether it works in 3.4 branch?
