The errors.log written by hdajackretask is empty, and I accidentally booted into the wrong kernel when submitting the original report, this actually also happens with

5.8.0-20-lowlatency #21-Ubuntu SMP PREEMPT Wed Sep 23 02:09:02 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Another interesting thind is that after a while some programs become unkillable, like sudo, or some daemons:
