This morning, I updated to Julia version 1.11.6 (2025-07-09), and I’ve been encountering the following recurring error:

Intel oneMKL ERROR: Parameter 6 was incorrect on entry to DLASWP.

This message repeats multiple times during execution, for example:

Intel oneMKL ERROR: Parameter 6 was incorrect on entry to DLASWP.  
Intel oneMKL ERROR: Parameter 6 was incorrect on entry to DLASWP.

I’ve spent the whole day investigating this online, and while it seems related to Julia’s linear algebra routines (possibly LAPACK bindings via oneMKL), I’m not making any progress. I tried to restructure my code to avoid heavy matrix operations by making it more iterative, but the error still persists.

One point of confusion: I’m running this on a Ryzen CPU (not Intel), so I don’t understand why oneMKL is involved in the first place. At this stage, I feel the issue may be beyond what I can solve alone
