Thanks for looking into this. Instability in the compiler has been an 
ongoing theme with ROCm on ppc64el.

Christian, your ggml package is the primary reverse dependency affected. 
While amd64 and arm64 can be binNMU'd, I think we might have trouble 
with ppc64el for a while. As I understand it, our options are basically 
to fix the bug in LLVM, find a workaround in rocblas, or RM rocblas 
rdepends on ppc64el. Do you have any preferences on how to proceed?

Sincerely,
Cory Bloor
