Hashcat 6.0.0 / CUDA crash (Solved)

[SquinklePhoom]

Hi,

New compiled Hashcat 6.0.0 (congrats btw!!),new Nvidia driver and supposedly newest CUDA toolkit as well - this makes hashcat crash. From searching, it looks like a cuda thing, however I cannot solve it - was wondering if anyone knows how to fix it?

Info below:

Code:

Code:

$ hashcat -I

This is on the completely updated system:

Code:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.4 LTS
Release:        18.04
Codename:      bionic

With the following kernel:

Code:

Linux gpuserver 4.15.0-106-generic #107-Ubuntu SMP Thu Jun 4 11:27:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Earlier Hashcat worked fantastic - few weeks old, dont remember the exact build. So 1) I dont know why it skips device #1 and 2) i dont know why it crashes. Any ideas? :-)

Update:  Someone is saying that it helps to downgrade CUDA - so Im getting CUDA 10.2 now to see if it helps. Will update post.
