I am running Ubuntu 22.04..2 lts 64bit with 16gb ddr3 ecc ram, fx 8300 cpu, rx 5500 xt gpu 8gb ddr6; i have reinstalled my video card drivers several times and even enrolled the MOK so the drivers can configure the modules correctly; i have reinstalled boinc a few times; but i still keep getting computation errors in all open-cl work units and no gpu crunching credit given due to the computation errors.

It turns out that my gpu, the rx 5500xt is likely defective, because i installed two rx 570s and they seem to be crunching fine. i guess the rx 5500 xt has been over it's life expectancy.
