Hi, 

Is there an update for this ticket? The issue is still easily be replicated in
the latest mesa on RadeonSI driver.

System information
Linux 5.2.2
Mesa-master 
Radeon RX 580 Series (POLARIS10, DRM 3.32.0, 5.2.2-htpc, LLVM 10.0.0)


I have tried different combination of llvm backend such as llvm-8, llvm-9, and
llvm-10. They produced the same error. Could this be a bug in amd llvm backend?

Previously, I have provided the api trace, I hope the trace can be used to
debug this issue.


I provided the latest error from today. They are the same error like before.
