matshch opened a new issue, #47564:
URL: https://github.com/apache/arrow/issues/47564
### Describe the bug, including details regarding any error messages,
version, and platform.
Here is the error that we see on our Apple M2 machine:
```
/tmp/nix-build-arrow-cpp-20.0.0.drv-0/source/cpp/src/arrow/util/io_util_test.cc:1099:
Failure
Value of: l2 >= 32 * 1024 && l2 <= 12 * 1024 * 1024
Actual: false
Expected: true
unexpected L2 size: 16777216
[ FAILED ] CpuInfo.Basic (0 ms)
```
As far as I can see, there are CPUs in the wild with up to 64 MiB of L2 CPU
cache, so it should be allowed.
### Component(s)
