SOLVED: OpenCL tonemapping stopped working

[caius]

I have a jellyfin server which used to do opencl tonemapping OK. I've noticed now that it gives an error when trying to transcode a file which requires tone mapping and playback does not start.

The server is a Celeron J4105 with UHD 600 graphics. Quicksync hardware acceleration works OK, as does VPP tone mapping. It's running on Ubuntu 24.04 LTS directly (ie not in docker).

Jellyfin version is 10.9.11.

It looks like some problem with the opencl driver but I'm not sure how to troubleshoot it. If I run clinfo that also crashes with the same error message. I'm not sure if this is a configuration error somewhere or if there's an issue with the driver itself. I'd be grateful if anyone has any ideas.
