Unfortunately without the reporters and discussion participants in Cc. Linux upstream is still broken since version 5.5. When "smartpqi: use host wide tagspace" [1] goes into mainline, we can submit it to stable, if nobody else does. This fixes the original problem and we got a patch with the same code change running in our 5.10 kernels.
