I now see that forgot to paste one important thing, that I found in dmesg and that may help:
[ 42.764276] traps: TT-Miner[14099] general protection fault ip:7f1ab0c20cd9 sp:7f1aa622d0a8 error:0 in libc-2.23.so[7f1ab0aba000+1c0000]
This is only thing, that I found for now.
Also tested on few other machines with different GPUs (P104-100 4GB), and on kernel 5.1.11 - and same error
