I've added it to the exclude-tests regexp in PR #113.
The test is problematic for multiple reasons, but we can only partially fix it. First problem that's actually solvable is that it uses a simple for loop + assignment, which Clang can optimize away based on -O flag (that's why i got different results than Henry on the same machine). On that machine, the test causes the GUI to "freeze" but it eventually recovers. If the test causes your laptop to freeze and not recover, i think that problem is out of scope for CHIP-SPV and is a linux kernel / driver issue.
BTW Intel's oneAPI docs recommend to disable GPU hangcheck for long-running tasks, so it seems they're aware of the "freezing".

What do I do to make this test fail? It passes for me after 200s

I reduced the runtime further on main please check if this is still causing you issues. @franz

@franz I waited 10 minutes at most, it could recover of course eventually :) Yep, sounds like a driver-side issue. Let's just exclude the test for now as it might hit end users and they think it's a CHIP-SPV issue.

Is it closed because it's no longer hanging after the reduced problem size?
