mac pro 5.1 mojave rx 580 crash at sleep

Hello everybody, thanks for any feedback.

I updated my cMP 4,1-5,1 from High Sierra to Mojave after installing the Saphire Nitro+ RX580.

Since Mojave was installed (over H Sierra), my mac keeps crashing and restarting at sleep.

I get mainly 2 kinds of reports -which I do not understand- one about kernel attack and one about bluetooth.

Any help / directions is greatly aprecciated!
