AMD Radeon Navi OpenCL Bug is polluting the SETI@Home database

A bug with the Radeon RX 5700-series "Navi" OpenCL compute API ICD (installable client driver) is causing the GPUs to crunch incorrect results for distributed compute project SETI@Home. Since there are "many" Navi GPUs crunching the project cross-validating each others' incorrect results, the large volume of incorrect results are able to beat the platform's algorithm and passing statistical validation, "polluting" the SETI@Home database. Some volunteers at the SETI@Home forums, where the the issue is being discussed, advocate banning or limiting results from contributors using these GPUs, until AMD comes out with a fix for its OpenCL driver.
