    opencl beignet haswell problem

    Code:
    kubuntu 20.04
    
    5.4.0-52-generic
    Hi everyone
    I'm trying to run the StarTools GPU accelerated version, but I'm getting errors. The program becomes unusable afterwards.
    Here is my clinfo:

    And here are the first 5 (of hundreds) of errors from beignet:

    Any ideas anyone?
