When I run a job the first time, it completes, albeit taking too much time for 10 passwords and the mouse pointer on the screen connected to RX Vega freezes sometimes:

“Перервано (збережено знімок оперативної пам’яті)” means “Segmentation fault”.

When I run the job the third time, `hashcat` just freezes:
Code:
$ env LANG=en_US.utf8 hashcat -w 1 -d 1 -a 0 -m 14600 luks_header darkweb2017-top10.txt

hashcat (v6.1.1) starting...
I run these commands from another seat connected to another videocard. This seat works as usual, no freezes. I already used `-w 1`, so the freezes are not caused by GPU overload. I do not know what else to do.

There is a similar thread.

I use the following “RadeonOpenCompute (ROCm)”.
Code:
$ pacman -Q hashcat
hashcat 1:6.1.1-1
$ pacman -Q rocm-opencl-runtime
rocm-opencl-runtime 4.0.0-1

I did not manage to replicate the ROCm “assertion failed” error. Freezes are easily replicated. `hashcat` freezes somewhere in the POSIX thread libraries:

RE: troubles on Radeon RX Vega 8 in AMD Ryzen 3 2200G - undeath - 01-27-2021

Crashes and freezes seen when using hashcat are pretty much always hardware errors. There's a slight chance it's a bug in the OpenCL runtime. If possible you can test on Windows, where a completely different OpenCL runtime is used.
