Bug Description

I run BOINC and have been running the Collatz project application for Intel GPUs for a few years. These have been working well.

On updating to Impish (for Hirsute) all 3 systems running this (3 Intel NUcs with i5-5250U, i3-8109U and i3-10110U CPUs) started to fail *every* Collatz job.

The error messages reported by the app are things like:

The verification of the steps for 10573729564897346322432 failed. The OpenCL device calculated 46747248 vs 487 steps by the CPU. Processing aborted.
Error: GPU steps do not match CPU steps. Workunit processing aborted.

The verification of the steps for 10585314751641536200690 failed. The OpenCL device calculated 1577457360 vs 611 steps by the CPU. Processing aborted.
Error: GPU steps do not match CPU steps. Workunit processing aborted.

FWIW, it started working again for me with Jammy.

Just have to wait for the project to come back after its move now....
