Description Orion Poplawski 2025-07-31 14:35:07 UTC 
causing openmpi and dependent packages to crash it SIGILL.  Upstream report is here: https://github.com/openucx/ucx/issues/10780

I'm disabling UCX support in openmpi on ppc64le to fix Fedora FTBFS isssue.  Looks like slurm also uses UCX, not sure if it is affected or not.

Reproducible: Always

f42 is also affected: https://koji.fedoraproject.org/koji/taskinfo?taskID=135571862
Comment 2 Orion Poplawski 2025-08-01 18:58:10 UTC 
That's interesting - since it's still UCX 1.17.0 there.
Comment 3 Karolina Surma 2025-09-29 14:21:09 UTC 
Hello. This is a bulk comment.

This package still needs to be rebuilt and/or shipped with Python 3.14.0rc3+ bytecode in Fedora 43.

The Final Freeze of Fedora 43 is scheduled to start next week. Please prioritize this bugzilla accordingly.

Thanks.

I think the last comment was meant to be applied to a different bug.  I don't believe ucx ships any python code.
