hashcat Forum - Hashcat 6.0.0 / CUDA crash (Solved)

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:

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.

Solved - driver incompability. Uninstall Nvidia driver and let the CUDA toolkit install the 450-driver series, and now its happy. About 5% faster with the driver updates :-)

Will leave the post if other runs into the same issue.

Thanks for the update SquinklePhoom.
Could you share the commands please? Same issue here.
I've done:

Code:
# Uninstall previous Nvidia driver

apt-get remove --auto-remove nvidia-cuda-toolkit nvidia-driver*

apt-get purge nvidia-cuda-toolkit nvidia-driver*

apt-get autoremove

# install CUDA, from official website

apt-get update

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin

sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600

wget https://developer.download.nvidia.com/compute/cuda/11.0.1/local_installers/cuda-repo-ubuntu1804-11-0-local_11.0.1-450.36.06-1_amd64.deb

sudo dpkg -i cuda-repo-ubuntu1804-11-0-local_11.0.1-450.36.06-1_amd64.deb

sudo apt-key add /var/cuda-repo-ubuntu1804-11-0-local/7fa2af80.pub

sudo apt-get update

sudo apt-get -y install cuda

I didnt use the repos - but your command set looks okay to me from a quick glance. I just uninstalled the nvidia driver ( --uninstall), and then installed it with the CUDA package. That was it :-)
