Description
Since we enabled metal testing with explicit root signatures, the WaveActiveMax.fp16 and WaveActiveMin.fp16 tests are consistently failing with a driver crash on the m2-mbp machine in the lab. Report here: https://github.com/llvm/offload-test-suite/pull/1061#issuecomment-4455026120
This doesn't seem to be an issue on M3 and later, but looks like it is likely a driver bug.

Research direction
Start by reproducing the WaveActiveMax.fp16 and WaveActiveMin.fp16 failures on the M2-MBP lab machine, then compare their behavior with M3 and later systems. Read the linked report and inspect the explicit root-signature testing change. Done means the driver crash is confirmed and an agreed test handling or fix is identified.
