Driver Hang/Crash using WebGPU in Chome

[RobConde]

Using the latest driver and Chrome, I am seeing that a simple WebGPU example using indirect draw calls causes the intel driver to hang on my hardware configuration. The issue is also reproducible on other machines with the same hardware configuration. The following github repository contains all system information and directions required to reproduce the issue: https://github.com/rconde01/intel_driver_indirect_call_hang

Let me know if any additional information is required.

Great! Looking forward to what the driver team finds.

@RobConde Can you try enabling the "unsafe WebGPU support" and share your results with me?

[RobConde]

The behavior was the same, but I'll mention that sometimes it works for a few seconds before failing. 

[Arturo_Intel]

@RobConde Thanks for confirming it!

I have the same behavior on my end, and I wanted to double check with you, 

now I am sure that is not an isolated issue.

Will continue to work on this case with the driver's engineer team.

Thanks for your help!

Any update/questions, I will be posting it here.

@Arturo_Intel Can you give me an update on this? It's been many months and you said you could reproduce the issue so I was hoping there might be some progress.

@RobConde 

Rest assure that we are working on this issue, unfortunately the root cause it not yet determined by our team. Seems to be one of those hard-to-find corner cases.

But not worry, our team is working hard to resolve the problem,
