System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: AMD Radeon RX 6950 XT ATI Technologies Inc. 4.5.0 Core Profile Context 23.7.2.230718

Blender Version
Broken: version: 3.6.1, branch: blender-v3.6-release, commit date: 2023-07-17 12:50, hash: 8bda729ef4dc
Worked: N/A

Rendering anything with the Cycles engine using HIP with the GPU Compute device crashes Blender immediately.

Exact steps for others to reproduce the error

Open Blender, edit preferences > Cycles Rendering Devices > HIP, then check the boxes like so:
Change the scene's render settings to use the Cycles engine with the GPU Compute device.
Click Render > Render Animation. Blender will crash.

These are the steps on any .blend file. It works with the default startup.blend.

Logs
Attached are the debug logs from running various .cmds from the blender install directory. The logs' filenames end with the name of the command that produced them.

with_flags.txt is the output generated in Powershell after starting Blender from the command line with the recommended flags.

The logs document Blender 3.6, but the same problem (superficially) appears in Blender 3.5.1 and 3.0.1.

Can you try disabling the usage of the CPU in your Rendering Devices tab. Also, if that does not work, try with only 1 of the 6950's selected. Let us know which of the combinations help or not.

Hi. None of these combinations make a difference, though it is worth noting that it is impossible for me to disable just one of the 6950s: they both toggle simultaneously.

If you are able, can you try a daily build of 4.0? There is a fix there for multi-device AMD setups that may help. It's scheduled to be included with 3.6.2 but there's no build yet for that version. It was primarily to fix CPU+GPU setups so I'm not hopeful it will fix the dual 6950's but it's worth a shot.

Sure, I will try in a moment.

Currently, I've rolled back my AMD drivers to 22.11.2. This seems to solve immediate crashing in some cases, but not with slightly more complex fluid simulations. I don't have logs/specifics for this behavior at this point since I can't consistently produce crashes.

I'll try updating back to 23.7.2 soon.

Trying to launch Blender 4.0 (93728fee53dc) just crashes immediately. Attached are the relevant logs.

Edit: It seems like the logs produced by the debug commands are broken; they are always produced as empty.

A further update: after attempting to launch Blender 4.0, all versions of Blender downloaded on my computer crash instantly.

Hi, is HIPRT enabled by any chance?
Have you recently switched from NVIDIA to AMD graphics card?

HIPRT was not enabled for any tests. This computer was built with the hardware in the OP- no substitutions have been made. So no, it has never had an NVIDIA card installed into it.

That's very strange. The only thing I could imagine impacting the ability to launch any version would be the driver changes that you did? If a full PC restart doesn't fix this then the situation is a bit beyond what we can support on the tracker here. There are tools to fully remove GPU drivers, rather than relying on the vendor's installer to do the right thing, and that may get the system back into a workable state.

impacting the ability to launch any version would be the driver changes that you did?... tools to fully remove GPU drivers,

@Robbi hi, did you try the clean installation of drivers?

Hi. Since my last post, I have been successfully using a nightly build of Blender 4.0 (commit 93728fee53) with Cycles GPU Compute, in addition to more intensive fluid simulations, without any crashes or significant errors that I can think of. Some notes:

Previous versions which did yield the crash with the original steps no longer crash
I am using the AMD driver version 23.7.2, the same as the OP
I had wiped old versions of drivers and restarted multiple times while still replicating OP

Basically, I have no idea 😅.

In summary, I can no longer trigger this issue on my machine anymore.

I wish I had a more exact set of steps to fix it to help anyone else with similar hardware and bugs (I have talked to at least two). Since I actually want to get work done with Blender and now have a working setup, I don't want to immediately do any more testing and risk breaking things.

Good to know that crash is no appearing anymore on your system :)
I'll close the report.
