Error "cuCtxCreate(): invalid device ordinal" with multiple sessions
#1
When trying to run multiple sessions at the same time the second session fails with the following error 
Code:
cuCtxCreate(): invalid device ordinal

I have a second system with similar hardware that works fine, but this new system isn't working the same. 

I've tried updating the NVIDIA driver to 418.67/430.34 and installed CUDA sdk, but nothing helped. Even tried downgrading the kernel from 5.0.0-15 to 4.18.0-25.
Code:
root@hostname:~# hashcat -I
hashcat (v5.1.0-1243-gd1f473d6) starting...
