<pre>
    The [InOneWeekend](https://github.com/llvm/llvm-test-suite/tree/main/External/HIP/workload/ray-tracing/InOneWeekend) and [TheNextWeek](https://github.com/llvm/llvm-test-suite/tree/main/External/HIP/workload/ray-tracing/TheNextWeek) tests in the External HIP test suite seem to fail intermittently.
This shows up as failures with the [clang-hip-vega20](https://lab.llvm.org/buildbot/#/builders/123) builder, e.g. [here](https://lab.llvm.org/buildbot/#/builders/123/builds/1622), but I also oberved it locally on my gfx1030 system, in ca. 5% of a longer series of repeated runs.

An example of the failure output is:
```
-- Testing: 6 tests, 6 workers --
Testing:  0.. 10.. 20.. 30.. 40..
