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.

Comment 4 Orion Poplawski 2025-09-30 02:00:16 UTC

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

Comment 5 Fedora Admin user for bugzilla script actions 2025-11-22 01:04:42 UTC

This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.

Comment 7 Zbigniew Jędrzejewski-Szmek 2026-06-26 07:42:44 UTC

Maybe the latest version helps? https://src.fedoraproject.org/rpms/ucx/pull-request/19

Comment 8 Zbigniew Jędrzejewski-Szmek 2026-06-29 20:19:52 UTC

OK I merge the PR?

Comment 9 Tom.Rix 2026-07-04 13:05:58 UTC

No.
This is a version update, not itself a bad thing, is there a subpart of that patch that fixes this problem ?

Comment 10 Zbigniew Jędrzejewski-Szmek 2026-07-06 11:42:26 UTC

I don't know. I don't know anything about ucx, I was looking into mpi and wanted to move things along. Applying the version bump seemed like the easiest approach, since it'd need to be done anyway. If it fixes the problem — great. If not, we can look for a different solution.

Comment 11 Aoife Moloney 2026-08-17 13:57:51 UTC

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
